In this work, lightweight granules of zeolite Na-P1 based on expanded glass aggregates were synthesized for the application in oil products’ sorption. The sorption of gasoline, diesel and silicone oil tests were also conducted for raw expanded glass, zeolite A, clinoptilolite and mineral sorbent available at a fuel station. All sorbents were also characterized in terms of the phase composition (X-ray diffraction) and structure (infrared spectroscopy). The zeolite Na-P1 granules achieved the highest values of sorption capacities (1.8, 2.1 and 2.6 g/g, respectively), which makes them promising materials for oils’ removal.

Activated carbon was oxidised with concentrated nitric acid and impregnated with urea to form nitrogen-containing groups. Such a support was impregnated with cobalt, copper or silver nitrates to obtain catalysts for the selective catalytic reduction of nitrogen oxides with ammonia. Infrared spectra confirmed the formation of carboxylic and other organic oxygen-containing groups during oxidation. Nitrogen-containing species resulted from urea thermal decomposition. The metal-containing samples were hydrophilic. Cobalt and copper were present in the samples as small Co3O4 and CuO crystallites, while silver occurred in the form of large metallic crystallites, as seen from the X-ray diffraction patterns. Low temperature N2 sorption revealed that all samples were microporous solids, and the chemical and thermal treatment did not change their textural properties. The copper admixture caused the highest NO conversion, but worsened the selectivity and thermal stability of functionalised carbon support.

Several mineralogically, chemically and texturally diverse minerals and waste materials were selected for the testing of elemental mercury capture in exhaust gas, namely tyre char resulting from the burning of pyrolytic rubber tyres, class C fly ash, mesoporous material type MCM-41 and glauconite. Each material’s mineralogical, chemical and textural characteristics were explored. In order to conduct experiments in conditions similar to those during the contact of sorbent with real coal exhaust fumes at a temperature of about 110-120°C, the experiments were carried out using a test device consisting of a furnace for burning powdered coals, a thermostatic cage for sorbent reactors and mercury gas analysers, which are able to measure and compare the effects of individual sorbents with exhaust gas. The study found that the best results for mercury sorption in the exhaust atmosphere were obtained for class C ash resulting from brown coal combustion.

The current work presents the results of seven sorbent samples investigated with respect to SO2 capture. The sorbents’ reactivity and capacity indexes were determined, and the tests were carried out in accordance with the ‘classical’ procedure for limestone sorbents. The reactivity indexes (RIs) of the tested samples were in the range of 2.57 and 3.55 (mol Ca)/(mol S), while the absolute sorption coefficients as determined by the capacity index (CI) varied between 87.9 and 120.6 (g S)/(kg of sorbent). Porosimetric analysis was also carried out and the specific surface area of the samples was found to be between 0.2 and 1.7 m2/g. The number of micro-, meso- and macro-pores in individual samples was determined from the corresponding pore size distribution histograms, and the values of sorbent RIs and CIs were correlated with the samples’ total porosity and specific surface.

The paper concerns the applicability of silver nanoparticles for reducing the emission of odours. Silver nanoparticles were successfully adsorbed on three different dolomitic limestone samples. In the next stage, wastewater from the meat industry was mixed with sorbents modified with a variable content of silver nanoparticles. After 4 days and 7 days, the concentration of ammonia was examined spectrophotometrically. Also, the degree of reduction of total odour concentration by olfactometric method was carried out. Depending on the concentration of the silver nanoparticles on the sorbents, the concentration of ammonia was 15-42 μg/cm3 for nAg content equal to 0.08%, while for sorbents containing approximately 36% of nAg the concentration of ammonia was 0.09-16 μg/cm3. A leaching test of nanosilver from sorbents confirmed that the particles were bound with the sorbents by strong bonds. The percentage of eluted silver increased from 0.67% to 11%, with increased initial concentrations of nAg on the sorbents from 0.18% to 0.37%.

Mineralogia

 Mineralogia (ISSN: 1899-8291, e-ISSN: 1899-8526), a free open access journal, publishes original research and review papers from broad fields of geochemistry, mineralogy, petrology, technical, experimental and applied mineralogy, and environmental sciences. Mineralogia (formerly Mineralogia Polonica) is an English language journal with 50 years long tradition. The journal’s subtitle, Geochemical, Mineralogical and Petrological Research, indicates the open character of the journal. The regular series Mineralogia is accompanied by the irregular series, including Mineralogia - Special Papers (containing conference abstracts) and Thematic Collections.    Publications in the scope of widely understood mineralogical sciences (mineralogy, petrology, geochemistry, environmental sciences, applied mineralogy, etc.)   Original research and review papers, letters (a short research paper), short notes (a brief communication), book reviews, and letters to editors with comments on papers published in Mineralogia    First issue of Mineralogia Polonica, the official Journal of the Mineralogical Society of Poland, was published in 1970 soon after foundation of the Society in 1969. Mineralogia Polonica, publishing in English from its beginning, has been very important for development of mineralogical sciences in Poland, exchange of scientific journals and international collaboration. Based on a long discussion with our colleagues from abroad we have noticed that the title suggests that the journal is focused on local mineralogical problems from Poland. To avoid this misunderstanding we have decided to modify the title and accordingly the journal cover. The new and simple title Mineralogia (with subtitle Geochemical, Mineralogical and Petrological Research) indicates an open character of the journal. We intend to publish original papers, review papers and short notes from broad fields of geochemistry, mineralogy, petrology, technical, experimental and applied mineralogy, environmental geochemistry and mineralogy. We have also decided to introduce changes in the organization of our Editorial Board to ensure high scientific level of journal and relatively short time-span between paper submission and publication.   The journal facilitates communication and promotes scientific research in the scope of:    descriptive mineralogy   experimental mineralogy   igneous petrology   metamorphic petrology   sedimentary petrology   hard rock geochemistry   geochronology and petrochronology   environmental mineralogy and geochemistry    Why subscribe and read    excellent source of outstanding interdisciplinary research papers in mineralogy, petrology, geochemistry and related disciplines;   over fifty years of publishing;   offers high-quality electronic publications (eISSN 1899-8526);   special issues publishing reviewed abstracts from conferences co-organized by the Mineralogical Society of Poland;    Why submit    fast, fair, and constructive single-blind peer review and editing;   no processing and no publication charges;   language-correction services for authors from non-English speaking regions;      Archiving   Sciendo archives the contents of this journal in Portico - digital long-term preservation service of scholarly books, journals and collections.   Plagiarism Policy   The editorial board is participating in a growing community of Similarity Check System's users in order to ensure that the content published is original and trustworthy. Similarity Check is a medium that allows for comprehensive manuscripts screening, aimed to eliminate plagiarism and provide a high standard and quality peer-review process.   Funding   Authors should list all funding sources in the Acknowledgments section.   ORCID   Mineralogia journal requires ORCID.   Ethical considerations   This journal follows the basic principles of the publishing process as documented by the Committee on Publication Ethics (COPE). The COPE’s guidelines focus mainly on issues related to publication in the medical literature; thus, not all the points are relevant to the Mineralogia journal. Although the essential ethical concerns considered while publishing in Mineralogia align with the COPE guidelines, Mineralogia is not bound by their defined processes.   Mineralogia otrzymała dofinansowanie z MNiE na lata 2022-2024 w ramach programu Rozwój czasopism naukowych (RCN/SN/0190/2021/1).
