氨基呲啶树脂对铟的吸附性能及机理

Properties and mechanism of sorption of aminopyridine resins for indium(Ⅲ)

比较了三种氨基吡啶树脂对铟的吸附性能。测定了4-氨基吡啶树脂对 In^(3+)的吸附、洗脱条件;树脂对 In^(3+)的吸附速率常数及活化能;反应的热力学函数;Freundlich 常数等。还对吸附反应的机理进行了探讨。

The comparison of the sorption propertiesof three kinds of aminopyridine resins for indium(Ⅱ)has been studied.The sorption and elutionconditions,sorption rate constant,activationenergy.thermodynamic data and Freundlich'sconstant,etc.of 4-APR for indium(Ⅲ)havebeen determined.The mechanism of sorption hasbeen studied
