Chemical Synthesis by Precipitation of Zinc Oxide for Boimedical Application

The objective of the study is the chemical synthesis of ZnO powders, from ZnCl₂ and NaOH solutions according to an appropriate procedure. The powders (a) and (b) obtained underwent various characterizations such as: optical microscopy, SEM, UV, BET, IR, XRD and antimicrobial activity. The results showed the inhomogeneous distribution, the nanometric size, the absorbance at 353 and 346 nm and the specific surface of 25.701 and 30.534 cm₂/g of the particles, the presence of all the characteristic bands of ZnO which was confirmed by XRD and very good bacterial sensitivity of the two ZnO powders.
