以黄土粘土（LC）为原料，采用丙烯酰胺（AM）、对苯乙烯磺酸钠（StS）等功能单体和交联剂（N，N-亚甲基双丙烯酰胺：MBA）进行表面接枝共聚改性，得到LC表面接枝共聚物（LC-PAmS）。采用傅里叶变换红外光谱（FT-IR）、热重分析（TGA）和扫描电镜（SEM）对其结构和组成进行了表征。研究了一种新型低成本黄土基高分子吸附剂对碱性品红的吸附性能。在优化条件下，室温下40 min，去除率可达98.4%。并对其吸附机理进行了探讨。结果表明，吸附等温线符合Freundlich等温式，吸附动力学符合准二级动力学模型。综上所述，LC-PAmS是一种具有实际应用价值的高分子吸附剂。
Loess clay (LC), a very abundant clay with granules and high hydrophilicity, was modified by surface grafting copolymerization of functional monomers, such as acrylamide (AM) and sodium p-styrene sulfonate (StS), and a cross-linking agent (N,N-methylenebisacrylamide: MBA), which afforded a LC surface grafting copolymer (LC-PAmS). Its structure and composition were characterized by Fourier transform infrared spectroscopy (FT-IR), thermal gravimetric analysis (TGA) and scanning electron microscopy (SEM). Acting as a novel and low-cost Loess-based polymer adsorbent, its adsorption behaviors were investigated with removing basic fuchsin (BF) in aqueous solution. After optimizing conditions, the removal rate got to 98.4% in 40 min at room temperature. Its adsorption mechanism was also investigated. It was found that the adsorption isotherm model could meet the Freundlich isotherm requirements and the dynamics were consistent with a pseudo-second-order kinetic model. In summary, LC-PAmS is a kind of polymer adsorbent for practically applied in wastewater treatment.
