摘　　要：用辛酸从硫酸铝溶液中萃取除铁，并用邻菲　啉分光光度法测定铁的含量。得出了萃取率与振荡时间、草取温度、pH值、相比的关系，以及提高萃取率的途径和条件，并应用于稀土尾矿的分选产品──高岭土精矿生产工业硫酸铝的试验中。The extraction of iron from solution of Aluminium sulfate was studied. The content of iron was determined by using spectrophotometric methods. There was a relationship between extraction efficiency and some influencing factors. A technique for improving extraction efficiency was described.
