Removal of Amoxicillin Antibiotic from Polluted Water by a Magnetic Bionanocomposite Based on Carboxymethyl Tragacanth Gum-Grafted-Polyaniline

Removal of antibiotics from contaminated water is very important because their harmful effects on the environment and living organisms. This study describes preparation a bionanocomposite carboxymethyl tragacanth gum-grafted-polyaniline γFe2O3 using an in situ copolymerization method as effective adsorbent for amoxicillin antibiotic remediation polluted water. The prepared materials were characterized by several analyses. vibrating sample magnetometer thermal gravimetric analysis showed that gum-grafted-polyaniline@ has magnetization saturation 25 emu g−1 stability with char yield 34 wt%, respectively. specific surface area about 8.0794 m2/g was obtained Brunauer–Emmett–Teller analysis. maximum adsorption capacity (909.09 mg/g) at pH 7, agitation time 20 min, bioadsorbent dose 0.005 g, initial concentration 400 mg/L. Freundlich isotherm pseudo-second-order kinetic models better fit experimental data. model chemical main mechanism bioadsorbent. In addition, compared to other reported adsorbents higher than adsorbents. These results show would be favorable
