Research Development of Separating Trace Heavy Metal Ions from CO_2 in Supercritical Phase by Using Complex Reaction

超临界络合反应分离技术是近年来发展起来的一项新技术。本文介绍了超临界络合反应分离技术的原理、分离过程、目前已开发出的络合剂、络合剂的选择原则以及影响因素,指出了当前超临界络合反应分离中存在的问题及发展方向。

Separation by using supercritical complex reaction is a new technique developed in recent years. In this paper, the mechanism and process of separation with supercritical complex reaction as well as developed complex agent, the selection principles of the complex agent and influence factors were introduced. Moreover, the problems existed in the separation process with supercritical complex reaction and developing direction of this technique were indicated.
