本文以磷酸三丁酯(TBP)为萃取剂,研究了在盐酸、硫酸体系中,介质酸度、萃取剂浓度、萃取时间等对砷(V)萃取的影响。确定使用50％TBP萃取砷(V)及反萃取的最佳条件。且将TBP和各种添加剂组成混合萃取剂对砷(V)的萃取作初步探索。
In this paper, tributyl phosphate (TBP) was used as extractant to study the effects of medium acidity, extractant concentration and extraction time on arsenic (V) extraction in hydrochloric acid and sulfuric acid. Identify the best conditions for extraction of arsenic (V) using 50% TBP and back extraction. And TBP and various additives mixed extractant for the initial exploration of arsenic (V) extraction.
