摘要 研究三烷基胺(N235)从硫酸介质中对Cr(Ⅵ)的萃取,考察了不同稀释剂、水相酸度、水相中Cr(Ⅵ)的浓度、萃取剂浓度、温度、相比等对萃取的影响.求得三烷基胺(N235)萃取Cr(Ⅵ)的过程热效应△H=-26.2 kJ/mol.研究表明三烷基胺(N235)是一种从废水中萃取分离Cr(Ⅵ)的优良萃取剂. The extraction performance of Cr（ Ⅳ） with trialkylamine from H2SO4 medium was studied. The influence of diluent, aqueous original acidity, the original concentration of Cr（Ⅳ） and extractant, extraction temperature and phase ratio were also tested. The value of AH of the process was calculated to be - 26.2 kJ/mol. The results showed that trialkylamine（ N235 ） was an excellent extractant to extract Cr（ Ⅳ ） from waste water.
