摘要

在简单体系中研究了以西瓜种子为吸附剂的新型环保活性炭对代表性抗生素磺胺甲基嗪(SMT)的去除效果。研究了pH、吸附剂用量、接触时间等实验参数。结果表明，弱化学键(π-π EDA相互作用)主导了SMT在西瓜种子上的吸附。该吸附剂对SMT的吸附具有重要作用，对西瓜种子的吸附量较高(90.78 mg/g)。研究了溶剂效应，发现电子-给体-受体(EDA)相互作用是SMT抗生素的主要吸附机制，吸附量随溶剂偶极矩的增大而增大。动力学研究表明，脱硝效率过程符合拟二阶模型，Langmuir等温线是拟合和描述该现象的最佳模型。

Removal of Antibiotic Sulfamethazine from Aqueous Media

The removal efficiency of Sulfamethazine as a representative antibiotic (SMT) on a new and eco-friendly activated carbon provided from watermelon seeds species as adsorbent has been studied in simple systems. Some experimental parameters, namely the pH, the amount of adsorbent and the contact time are studied. The results showed that the weak chemical bond (π-π EDA interaction) dominated the sorption of SMT to watermelon seeds. The present adsorbent played an important role in the sorption of SMT, leading to a higher sorption capacity onto watermelon seeds (90.78 mg/g). The solvent effect is been studied to show that the electron-donor-acceptor (EDA) interaction is the main adsorption mechanism of SMT antibiotic and that adsorption capacity increases with the increase of dipole moment of solvents. A kinetic study showed that the removal efficiency process followed the pseudo-second-order model and the Langmuir isotherm was the best model to fit and describe the phenomenon in the single system.
