THE SORPTION BEHAVIOR OF D751 CHELATE RESIN FOR EUROPIUM
【摘要】 用D751树脂对Eu3+进行吸附性能研究。测定了树脂对Eu3+的吸附容量409.7mgEu3+·g-1树脂,温度对吸附分配系数的影响,焓△H=25.85×103J·mol-1。表观吸附速率常数及表观活化能Ea=26.45×103J·mol-1。并用化学法及红外光谱等探讨了吸附机理。
【Abstract】 The sorption behavior of D751 chelate resin for europium ion has been studied. The sorption capacity of the resin for Eu3+ is 409. 7mg Eu3+·g-1 resin. The sorption enthalpy △H is 25. 85×103 J·mol-1. The apparent sorption activation energy Ea is 26. 45×103 J·mol-1. The influence of temperature on the sorption distribution coefficent Kd and the apparent sorption rate constant have been determined. The sorption mechanism has been discussed by using chemical method and infrared spectra.
