研究二（二苯基磷酰）胺（Htpip）对Cr（Ⅲ）的吸附性能,探究一定的p H值、吸附时间下,Htpip的用量、Cr（Ⅲ）的初始浓度对吸附的影响。根据对材料的FT-IR、SEM等表征,结合吸附实验结果探讨吸附机理,表明亚氨基和磷酸在吸附过程中发挥了重要作用。实验结果显示,Cr（Ⅲ）吸附容量随吸附剂投加量的增加而减少,随离子初始浓度的增大而增加。Htpip对Cr（Ⅲ）的吸附行为遵循准二级动力学方程,吸附过程符合Langmuir方程,饱和吸附量达到58.39mg·g^-1。

To investigate the Tetraphenylimidodiphosphinate （Htpip） adsorption performance of Cr （VI）, and explored the effects of Htpip dosage and initial concentration of Cr （VI） on adsorption with the certain pH value and adsorption time. According to the characterization of samples including FT - IR, SEM and the adsorption mechanism of adsorption experiment, the results indicated that the amino and phosphate played an important role in the process of adsorption. The experimental results shows that Htpip adsorption capacity of Cr （VI） decreased...
