在25±1℃下用分配法研究了HDEHP-煤油从硫酸盐介质中萃取Mn(Ⅱ)以及HDEHP-TOPO-煤油协同萃取Mn(Ⅱ)的机理;考察了介质pH、金属浓度、萃取剂浓度、温度和中性膦氧试剂对萃取的影响。
The mechanism of extraction of Mn (Ⅱ) from HDS-kerosene from sulfate media and synergistic extraction of Mn (Ⅱ) from HDEHP-TOPO-kerosene was studied by using partition method at 25 ± 1 ℃. The influences of medium pH, metal concentration, extractant concentration Effect of Temperature and Neutral Phosphine Reagents on Extraction.
