732阳离子交换树脂对钙镁离子的吸附性能研究

摘要

研究了732阳离子交换树脂对钙、镁离子的吸附,分别考察了树脂对钙、镁离子吸附的类型、速率及吸附过程的各热力学参数.结果表明:732阳离子交换树脂对钙、镁离子的吸附性能相近,均为Langmuir型吸附,并且是一个吸热、自发的熵增过程.%The adsorption of calcium ion and magnesium ion by 732 cation exchange resin was studied. The adsorption type, adsorption rate and thermodynamic parameters of resin for the two ions were investigated. The results showed that the adsorption properties of resin for the two ions were similar. The adsorption type was the type of Langmuir, and the adsorption was an endothermic and spontaneous entropy increase process.
