[P6,6,6,14][SCN], methyltrioctylammonium chloride (Aliquat 336), as well as bis(2,4,4-trimethylpentyl)phosphinic acid (Cyanex 272) were also used in the extraction of metals from the leachate. Two DESs (1) choline chloride + lactic acid, 1:2} and (2) choline chloride + malonic acid, 1:1} were used in the extraction of metals from the solid phase. The extraction behavior of metals with DESs was compared
介绍了使用离子液体 (IL)、深共晶溶剂 (DES) 和有机磷基酸 (Cyanex 272) 从废旧印刷电路板 (WPCB) 中提取金属的方法。该研究旨在评估新浸出液应用的有效性,以及采用或不采用浸出过程从浸出液和固相中提取金属的新方法。已经使用流行的离子液体详细研究了从液体渗滤液相中提取溶剂,例如溴化四辛基鏻,[P 8,8,8,8 ][Br] 和氯化三丁基十四烷基鏻,[P 4,4,4,14 ][ Cl] 使用水性双相系统 (ABS) 方法。三己基十四烷基鏻双(2,4,4-三甲基戊基)次膦酸盐,[P 6,6,6,14 ][Cyanex272],([P6,6,6,14 ][BTMPP])、硫氰酸三己基十四烷基鏻、[P 6,6,6,14 ][SCN]、甲基三辛基氯化铵 (Aliquat 336) 以及双(2,4,4-三甲基戊基)次膦酸 (Cyanex 272) 也用于从渗滤液中提取金属。两种
