The article introduced Gold Potassium Citrate, the new plating gold material which can highly improve the PCB industry clean production. Based on the product analysis, Gold Potassium Citrate is environment friendly product and should be promoted in large scale.% 丙尔金镀金新材料主要是由三氯化金、丙二腈和柠檬酸在特定条件下发生络合反应获得,产品本身不含氰,但在产品溶液中确能检测出微量的氰化物,这是我国在产品分析检验方法上,要把被检测出的残留丙二腈含量全部计入到氰化物总量分析结果中所致,且检测值很低,可忽略不计.另外,据国家权威机构鉴定,丙尔金不属危险化学品,属实际无毒产品.同时,排放废水中的氰化物含量都低于0.3mg/L,甚至可低到0.01mg/L.因此,丙尔金镀金新材料不存在环保问题.正因为此,丙尔金镀金新材料不仅是无毒的、清洁的、环保的,应大力推广应用.
