Abstract

A hybrid type of ion exchanger polyacrylamide Sn(IV) molybdophosphate has been synthesized by mixing polyacrylamide into inorganic material Sn(IV) molybdophosphate. The physicochemical properties of this material were determined using X-ray diffraction, infrared spectroscopy, SEM, surface area (BET), and thermal analysis (TGA and DTA). Sorption uptake has been performed by batch experiments as a function of process parameters (such as temperature and pH). Experimental results have showed that the removal percentages increasing of metal ions with increasing pH. Thermodynamic parameters such as ΔG*, ΔS* and ΔH* have been calculated from the adsorption of Co(II) and Cr(III) onto polyacrylamide Sn(IV) molybdophosphate.

聚丙烯酰胺钼磷酸锡(IV)对钴和铬的吸附行为

摘要

通过将聚丙烯酰胺混合到无机材料钼磷酸锡(IV)中，合成了一种混合型离子交换剂聚丙烯酰胺钼磷酸锡(IV)。使用 X 射线衍射、红外光谱、SEM、表面积 (BET) 和热分析（TGA 和 DTA）测定该材料的物理化学性质。吸附吸收已通过批量实验进行，作为过程参数（例如温度和 pH 值）的函数。实验结果表明，随着pH值的增加，金属离子的去除率增加。热力学参数，例如 ΔG*、ΔS* 和 Δ< /span>* 根据 Co(II) 和 Cr(III) 在聚丙烯酰胺 Sn(IV) 钼磷酸盐上的吸附计算得出。H
