چکیده مقاله:

In recent years, there has been an increase in the consumption of pharmaceuticals, especially antibiotics. Tetracycline (TC) is one of the widely used antibiotics, as it causes resistance to all microorganisms in ecosystems. In addition, it is classified as a controlled antibiotic. In this work, the efficiency of TC drug degradation via photolysis and hetero-generous photo catalytic methods is studied under effect of several volumes of H۲O۲ (۰-۴ mL) as an oxidizing agent. Characterization of the sample was carried out via UV-visible spectroscopy, XRD, FESEM, EDX, and TEM. The reveal results the photocatalytic degradation of TC drug is ۹۲.۶۷ %, at the best conditions weight of catalyst ZnO NPs ۰.۳ g, volume of hydrogen peroxide (۳ mL), and concentration of TC drug ۵۰ mg/L, pH=۶, at irradiation time ۶۰ min. H۲O۲ doses (۰ and ۴ mL) appear to have important variances in the first ۱۰ min of the reaction for ۴ mL of H۲۰۲ comparative with the solution without H۲O۲ giving the best PDE% (۹۸.۴۴%). The (PDE%) rises as concentration of TC drugs decreases from (۹۲.۶۷%-۲۹.۷۶%), but light intensity increases. Regeneration/recycling of ZnO NPs the photo catalytic degradation efficiency was ۸۸.۹ %, ۸۲.۸ %, and ۷۷.۵% through ۴ cycles compared to standard solution(fresh) was ۹۲.۶۷ %.
