摘　　要：在二甲酚橙 - CTMAB-硼砂显色体系中 ,不必分离掩蔽 ,同时测定了相互干扰严重的铜、镍、镉和锌 ,4种组分的分析误差不大于 2 .4%。The multi component standard-addition spectrtophotometry with orthogonal regress design was applied to determine copper,nickel,cadmium and zinc simultaneously in waste water without separating and masking. The relative error of determination of the four components was less than 2 4%.
