摘　　要：采用甲醛肟-锰、镍显色体系,应用人工神经网络分光光度法,对吸收光谱严重重叠的两组分锰、镍同时进行测定。应用于工业废水中锰(Ⅱ)和镍(Ⅱ)的同时测定,回收率在95%～102%之间。Manganese （Ⅱ） and nickel （Ⅱ） were determined simultaneously by spectrophotometry using formaldoxime （FMX） as color reagent. Serious over-lapping of the spectra of complexes of Mn （ Ⅱ ）-FMX and Ni（ Ⅱ ）-FMX was resolved by using the algorithm of artificial neural network （ANN）. In application of the proposed method to the simultaneous determination of Mn（ Ⅱ ） and Ni（ Ⅱ ） in industrial waste water, values of recovery in the range of 95%--102% were obtained.
