Abstract

The water extract of Petasits hybridus leaves was used in this study to create the high-performance ZnO/Fe₃O₄@GO magnetic nanocomposites, which were then used as an environmentally friendly adsorbent for the removal of amoxicillin (AMX) and cefixime (CFX). The initial concentrations of CFX and AMX, contact time, solution pH, temperature, and adsorbent dose were among the adsorption parameters that were examined. The pseudo second-order and Langmuir models, respectively, provided good fits to the adsorption kinetic and isotherm. When CFX and AMX are adsorbed onto ZnO/Fe₃O₄@GO nanocomposite, the initial amounts are 10 mg. Moreover, ZnO/Fe₃O₄@GO adsorb CFX and AMX at pH values of 6 and 8.5 respectively. The low cost of the adsorbent, its great efficiency, and its ease of use are its advantages.
