高分子冠醚聚合物对水溶液中微量金属离子的富集分离

Collection-Seperation of the Traces of Some Metallic Jons in Aqueous Solutions with Polymeric Crown Ethers

本文报导动态法研究高分子冠醚聚合物对水液中微量金属离子的吸附作用。测定了各种聚合物冠醚的富集百分率、富集容量、洗脱效率和富集分离效率;并对定影废液中微量金属银的分离、提取、回收进行了初步研究。

The adsorption of tne traces of some metallic ioas from aqueous solutions by the polymeric crown ethers is studiel with a dynamic method.The collec-ting efficiencies and capacities of several poglmeric crown ethers for the me-tallic ions and the efficiencies of wash-resmov ing the metallic ions adsorbed from the crovn ethers are measured. The col lee tion-seperat ion and recoyver of the trace silver from fixing bath is investigated primarilg.
