以偶氮氯膦Ⅰ作显色剂测定铝、锌合金中的镁,铝合金中的锆以及铜合金中的铝都得到应用,测定钢铁中的铝本刊曾有报道,本文应用铜试剂分离包括基体铁在内的大部分共存元素后进行测定得到了满意的结果。一试剂王水:2份盐酸+1份硝酸 EGTA-Pb混合溶液:取乙二醇二乙醚二胺四乙酸(简称EGTA)1.9g,加水200ml,加热,滴加氢氧
Aluminum chlorophosphate I as a reagent for determination of aluminum, magnesium in zinc alloys, zirconium in aluminum alloys and aluminum in copper alloys are used in the determination of aluminum in steel. It has been reported that this article uses copper reagent separation Satisfactory results were obtained after the determination of most of the co-existing elements including matrix iron. A reagent aqua regia: 2 parts of hydrochloric acid + 1 part of nitric acid EGTA-Pb mixed solution: take ethylene glycol diethyl ether diamine tetra acetic acid (EGTA for short) 1.9g, add water 200ml, heating, dropping hydrogen
