用D751树脂对Eu~(3+)进行吸附性能研究。测定了树脂对Eu~(3+)的吸附容量409.7mgEu~(3+)·g~(-1)树脂,温度对吸附分配系数的影响,焓△H=25.85×10~3J·mol~(-1)。表观吸附速率常数及表观活化能E_a=26.45×10~3J·mol~(-1)。并用化学法及红外光谱等探讨了吸附机理。
Study on Adsorption Properties of Eu ~ (3+) with D751 Resin. The adsorption capacity of 409.7mgEu ~ (3+) · g ~ (-1) resin with different Eu ~ (3+) adsorption capacity was determined. The enthalpy △ H = 25.85 × 10 ~ 3J · mol ~ ( -1). Apparent adsorption rate constant and apparent activation energy E_a = 26.45 × 10 ~ 3J · mol ~ (-1). The adsorption mechanism was discussed by chemical method and infrared spectroscopy.
