基于十八烷基二甲基苄基氯化铵(BDMSAC)与Au(CN)-2络阴离子生成的离子缔合物可被C18反相键合硅胶固相萃取柱萃取、富集,建立了一种从碱性氰化液中高富集倍数固相萃取金的方法。该方法用于从碱性氰化液中固相萃取痕量金,萃取回收率可超过98%,同时研究了C18反向固相萃取金的机理,也创造性地提出了一种从碱性氰化液中提取金的新工艺。
The ion-association compounds based on the tetradecyl dimethyl benzyl ammonium chloride (BDMSAC) and Au (CN) -2 complex anions can be extracted and enriched by C18 reversed-phase bonded silica gel solid-phase extraction column A method of high enrichment multiples solid phase extraction gold from alkaline cyanide solution. The method was applied to the solid-phase extraction of trace gold from alkaline cyanide solution. The extraction recovery rate can exceed 98%. At the same time, the mechanism of C18 reversed-phase solid-phase extraction of gold was also studied. New solution of gold extraction process.
