本文采用溶剂萃取法净化磷酸,在不同的磷酸浓度和不同的初始相比的条件下研究了萃取剂对磷酸和硫酸根的萃取率和萃取剂对磷酸体系的选择性.研究结果表明:萃取剂对低浓度的磷酸不表现出萃取性能,磷酸萃取率和选择性随着相比的增大而增加,硫酸根的萃取率呈相反的变化趋势.

A study of purification of phosphoric acid by solvent extraction was carried out. The extraction rates of phosphate and sulfate was studied under different phosphoric acid concentrations and initial phase ratio. The results suggested that the phosphate extraction rate and the selectivity is increased with the increase of initial phase ratio, however, the sulfate extraction shows the opposite trend.
