摘要(Abstract)：

研究了采用熔盐电解法制备二硫化钼,然后将其与磷酸银复合制备磷酸银/二硫化钼(Ag_3PO_4@MoS_2)吸附剂,用以吸附去除水溶液中的碘离子。用Zeta电位仪、傅里叶变换红外光谱仪(FT-IR)和X-射线衍射仪(XRD)表征所制备的Ag_3PO_4和Ag_3PO_4@MoS_2吸附剂,并通过批次试验考察溶液pH、接触时间、碘离子初始质量浓度、温度等因素对Ag_3PO_4和Ag_3PO_4@MoS_2吸附碘离子的影响。Ag_3PO_4和Ag_3PO_4@MoS_2对碘离子的吸附试验结果表明:在溶液pH=7.0、吸附平衡时间分别为120 min(Ag_3PO_4)和60 min(Ag_3PO_4@MoS_2)条件下,吸附过程符合准二级动力学模型,且为自发吸附过程;Ag_3PO_4和Ag_3PO_4@MoS_2对碘离子的吸附均符合Langmuir模型,饱和吸附量分别为617.28 mg/g(Ag_3PO_4)和628.93 mg/g(Ag_3PO_4@MoS_2)。Ag_3PO_4@MoS_2对碘离子的吸附速度很快,吸附效率很高,是一种潜在的高效吸附材料。
