| The abuse of antibiotics caused serious environmental pollution. The biomass material adsorbent-Pinus Massoniana pine needles and synthetic material of polymer adsorbent -strongly basic anion exchange resin would be used in the experiment though analyzing and comparing some different kinds of removal techniques. The removal of antibiotics in water using adsorption was analyzed in this paper. The experimental results showed that adsorption of pines needles and resin for sulfamethazine in water all complied with Langmuir isotherm equation model well, and indicated that the physical adsorption plays a principal role. The pines needles adsorption kinetics complied with the first-order equation, while the resin adsorption kinetics complied with the second-order equation. The pH had a great influence on the saturated adsorption capacity, and it was larger when the pH approached neutral value. The adsorption capacity was 0.229mg/g and 0.244mg/g. The adsorption capacity increased with increasing temperature when the temperature was blow 20 "C, however, adsorption capacity could saturated when the temperature over 20? and the adsorption time was enough. Through the experiment conclusion could know that, using the pine needles as adsorbent to remove the antibiotic substances in water has great application prospect, and it is worthy of further discussion. |
