Study on Synthesis and Adsorption Behavior for Uranyl of Chitosan-based Adsorbents
摘要
Abstract
Biopolymeric adsorbents with ammonio were synthesized based on chitosan polymeric matrixes by chemical modification .The adsorbents were characterized by FTIR and determination of ammonio content .T he effect of pH of uranium solutions ,different ethyleneamines modification and doses of crosslinking agent on adsorption properties of the adsorbents were examined .Chitosan-based adsorbent (CATT ) modified with triethylenetetreamine could remove uranium effectively from low concentration uranyl solutions ,the removal rate was more than 94% .It was expected to settle some problems ,such as process complex ,high cost of raw materials for waterwaste treatment in uranium hydrometallurgy .关键词
