Abstract

An environmentally friendly solvent, namely, polypropylene glycol 425, has been proposed for the extraction of metal ions from chloride solutions using trioctylmethylammonium thiocyanate. The quantitative characteristics of the extraction of Fe(III), Zn(II), and Mn(II) using trioctylmethylammonium thiocyanate in the polypropylene glycol 425–NaCl–H2O system have been found. For extracting Fe(III), Zn(II), and Mn(II), it has been shown that the patterns of the extraction of metal ions remain unchanged and the replacement of the solvent does not lead to the loss of extraction capacity for trioctylmethylammonium thiocyanate. The mechanism of the extraction of the metal ions under study has been determined. The proposed extraction system can be used to purify Mn(II) from Fe(III) and Zn(II).

摘要

已经提出了一种环境友好的溶剂,即聚丙二醇425,用于使用硫氰酸三辛基甲基铵从氯化物溶液中萃取金属离子。已发现在聚丙二醇425–NaCl–H 2 O系统中使用三辛基甲基铵硫氰酸盐萃取Fe(III),Zn(II)和Mn(II)的定量特征。对于萃取Fe(III),Zn(II)和Mn(II),已显示金属离子的萃取模式保持不变,并且溶剂的替换不会导致三辛基甲基铵的萃取能力的损失。硫氰酸盐。已经确定了所研究金属离子的提取机理。所提出的提取系统可用于从Fe(III)和Zn(II)中纯化Mn(II)。
