Polyaniline (PANi) was hybridized with a bagasse (BG) substrate to treat Dichlorodiphenyltrichloroethane (DDT), dichlorodiphenyldichloroethylene (DDE), and dichlorodiphenyldichloroethane compounds, which are persistent organic pollutants (POPs) causing environmental contamination. The PANi/bagasse (PA/BG) composite was synthesized using ammonium persulfate and sulfuric acid, achieving efficiencies ranging from 82.63% to 86.92% with different ratios of PANi monomer to BG. Infrared spectroscopy (IR) and scanning electron microscopy (SEM) were used to characterize the synthesized materials. The adsorption capacities of DDT, DDD, and DDE compounds were investigated under various conditions, including adsorbent type, adsorption time, adsorbent dosage, and adsorbate concentration. Both Langmuir and Freundlich isotherm models were applied to evaluate the adsorption process, and the results indicated that both models were suitable for describing the adsorption of DDT, DDD, and DDE by the PANi/bagasse composite material.
将聚苯胺(PANi)与甘蔗渣(BG)基质杂交,以处理作为造成环境污染的持久性有机污染物(POPs)的二氯二苯三氯乙烷(DDT)、二氯二苯二氯乙烯(DDE)和二氯二苯二氯乙烷化合物。使用过硫酸铵和硫酸合成了PANi/甘蔗渣(PA/BG)复合材料,在不同比例的PANi单体与BG条件下,实现了82.63%至86.92%的效率。利用红外光谱(IR)和扫描电子显微镜(SEM)对合成材料进行表征。在包括吸附剂类型、吸附时间、吸附剂用量和吸附质浓度等各种条件下,研究了DDT、DDD和DDE化合物的吸附容量。应用朗缪尔和弗伦德利希等温线模型评估吸附过程,结果表明这两种模型均适用于描述PANi/甘蔗渣复合材料对DDT、DDD和DDE的吸附。
