Abstract

In the present study, poly(styrene-co-acrylonitrile) nanofibers incorporated with carbon nanotubes (CNTs) and graphite were created by the electrospinning method. Monitoring the effectiveness of the carbonaceous materials (CNTs and graphite) in the prepared nanofibers and evaluating their efficiency removal against sources of non-point resource pollution sources such as simazine pesticide. The influence of the removal process parameters concerning the batch mode such as pH, temperature, concentration, and nanofibers dosage was monitored. According to the results, the adsorption capacity of P(St-co-AN) nanocomposites toward simazine increased at pH > 5 and by the raise the concentration of nanofibers doses. Generally, CNTs-based form of P(St-co-AN) nanofibers has a higher uptake capacity than that achieved by the graphitic form. The experimental data showed the applicability of pseudo-2nd-order mechanism for the adsorption of simazine onto P(St-co-AN) nanocomposites with better linearity of the Langmuir model.

接种吸附材料的聚苯乙烯-丙烯腈复合纳米纤维减少面源污染

摘要

在本研究中,聚(苯乙烯-与碳纳米管(CNT)和石墨结合-丙烯腈)纳米纤维通过电纺方法创建的。监测制备的纳米纤维中碳质材料(CNT和石墨)的有效性,并评估其对面源资源污染源(如辛嗪农药)的去除效果。监测去除工艺参数对间歇模式的影响,例如pH,温度,浓度和纳米纤维用量。根据结果​​,P(St- co- AN)纳米复合材料对simazine的吸附能力在pH> 5时增加,并且通过增加纳米纤维剂量的浓度而增加。通常,基于CNT的P(St- co-AN)纳米纤维比石墨形式具有更高的吸收能力。实验数据表明,伪二阶机理对Simazine吸附在P(St- co- AN)纳米复合材料上具有更好的线性度。
