摘　　要：报道了光度法联合测定铝镍钴永磁合金中镍、铝、铜的分析方法．试样用硝酸（1＋1）溶解，高氯酸冒烟处理，用丁二酮肟光度法测定镍，铬天青S光度法测定铝，双环已酮草酰二腙光度法测定铜。方法操作简单、快速、准确．A method for the dermination of nickel,aluminum and copper in permanent magnetic alloy of aluminumnickel-cobalt by photometry was proposed in the paper. The sample was dissolved by HNO3（1＋1） and smoked by perchloric acid .The nickel was determined by dimethyl glyxime photometry, The aluminum was determined by chrome azurol-S photometry and the copper was determined by BCO photometry. This method is convenient, rapiol and accurate.
