Abstract

Polyurethane was prepared from toluene diisocyanate (TDI) and triethanolamine esters. The equilibrium and kinetic characteristics of the uranium sorption onto polyurethane were determined. The adsorption factors were optimized. The adsorption capacity for uranium reaches 70 mg/g and agrees with the value obtained by fitting with the Langmuir isotherm (75 mg/g). The adsorption process follows pseudo-second-order rate equation.

使用合成聚合物从硫酸盐介质中吸附铀；动力学特性

摘要

聚氨酯是由甲苯二异氰酸酯（TDI）和三乙醇胺酯制得的。确定了铀在聚氨酯上的吸附平衡和动力学特征。优化了吸附因子。铀的吸附容量达到70 mg / g，与通过Langmuir等温线拟合得到的值（75 mg / g）一致。吸附过程遵循伪二级速率方程。
