摘要： 本文研究了PAN负载的聚氨酯泡沫在静态法和动态法对水溶液中Cu、ZnCd离子的萃取行为,同时试验了pH、阴离子以及流速的影响。回收率试验表明,该法能定量捕集天然水中Cu、Zn、Cd离子,结果令人满意。

Abstract: This paper describes a method of solid-liquid extraction to replace the conventional solvent extraction, using FANloaded polyurethane foams in batch and column operation for preconcentration of the trace Cu, Zn, Cd in aqueous solution. The effects of pH, various anions in batch method and flow-rate in column process on the extraction behavior of Cu, Zn, Cd have been investigated. Preconcentration of Cu, Zn, Cd ions from natural water is successful.
