摘要
Abstract
The diffusion behavior of copper and zinc cyanide complexes in alkaline solution on ion exchange fiber（IEF） was studied applying Boyd film diffusion equations and Fan Shan yang’s diffusion models.Adsorption mechanism of copper and zinc cyanide complexes was studied by analyzing the changes of the functional group position and the element content on IEF before and after desorption.The results showed that the adsorption process of copper and zinc complexes by IEF was controlled by the main film diffusion at the initial stages of reaction and by diffusion gap at the late stages of reaction.And the reasons for different adsorption rates at different stages are explained by using IEF in the aqueous colloidal substances with similar double-layer structure.In the adsorption process,though the adsorption rate at different stages changes,the fiber adsorption for copper and zinc cyanide complexes coincides with ion exchange adsorption mechanism.关键词
