Abstract

A choline chloride–sulfosalicylic acid deep eutectic solvent (DES) is proposed for dissolving the oxides Co(II), Cu(II), Zn(II), Fe(III), Ni(III) and Mn(III). An experimental study of the influence of the dissolution time, solid : liquid mass ratio, temperature, and molar ratio of choline chloride and sulfosalicylic acid on the dissolution of metal oxides in the proposed DES has been carried out. The mechanism of dissolution of the investigated metal oxides has been established. It is shown that choline chloride–sulfosalicylic acid DES can potentially be used for the efficient leaching of metals from components of spent chemical power sources.

金属氧化物在氯化胆碱-硫代水杨酸低共熔溶剂中的溶解

摘要

提出了一种氯化胆碱-磺基水杨酸低共熔溶剂 (DES) 来溶解氧化物 Co(II)、Cu(II)、Zn(II)、Fe(III)、Ni(III) 和 Mn(III)。已经进行了溶解时间、固液质量比、温度和氯化胆碱和磺基水杨酸的摩尔比对金属氧化物在提议的 DES 中溶解的影响的实验研究。已经建立了所研究金属氧化物的溶解机制。结果表明,氯化胆碱-磺基水杨酸 DES 可潜在用于从废化学电源的组分中有效浸出金属。
