含铬废水的萃取回收研究

THE RESEARCH OF EXTRACTION WITHDRAWAL OF WASTEWATER CONTAINED CHROMIUM

本文进一步论述了用磷酸三丁酯作萃取剂,萃取回收含铬废水中Cr(VI)的两个重要问题:酸度对温度影响萃取效果的抵消,有机相的氧化。该研究能更好地用于工业生产。

This paper further deals with two important problems about extracting and withdrawing Cr(Ⅵ)from waste water contained chromium by using tributyl phosphate as extractant—degree of the acid remove effect of extraction influenced by the temperature and oxygenation of organic phase. This method agrees to the industrial production even better.
