采用上升液滴法研究了异戊醇从氯化物-磷酸体系中萃取磷酸的动力学,结果表明磷酸的初始正向萃取速率随两相界面积、水相初始磷酸、盐酸浓度的增大而增大,异戊醇对磷酸的萃取可能属扩散控制模式。在实验基础上建立了如下的萃取动力学方程:Rp=4.719×10-8C1.802pC1.004cl,其计算值与实验值的相对标准偏差为5.02%。
The kinetics of iso-amyl alcohol extraction from phosphoric acid-chloride system was investigated by the ascending drop method. The results showed that the initial positive extraction rate of phosphoric acid increased with the increase of the interfacial area of the two phases and the initial concentration of phosphoric acid and hydrochloric acid in the aqueous phase Large, isoamyl alcohol extraction of phosphoric acid may be diffusion control mode. The following extraction kinetic equation was established on the basis of experiments: Rp = 4.719 × 10-8C1.802pC1.004cl, the relative standard deviation between calculated and experimental values was 5.02%.
