在不同温度,不同树脂用量下进行吸附动力学实验,结果表明,D392阴离子交换树脂对色素的吸附等温线符合Freundlich模型＞符合Langmuir模型,它对色素的吸附可能是多分子层的,表现为吸热的化学吸附过程.此外,静态吸附速率曲线符合Lagergern一级速率方程,吸附速率受颗粒内扩散和膜扩散的共同控制.

Under the different temperatures and amount of resin, the adsorption dynamics experiments were carried on, and the results showed that the D392 anion resin for the pigment adsorption isothermal conformed to the Freundlich model＞Langmuir model, absorption of the pigment would be more molecular levels, displayed for the heat-absorbing of the chemical adsorption process. In addition, adsorption rate curve of the static state conformed to the Lagergern for first-level rate equation, the rate of absorption by the particles proliferation and membrane proliferation would be jointly controlled.
