摘要
研究应用双波长K系数—标准加入吸光光度法同时测定锰和锌二组分混合物.试验确定了锰和锌测定中K_(Mn)与K_(Zn)的回归方程.对合成试样、人发试样测定,结果满意.
It is reported in this paper that the simultaneous determination of manganese and zinc in a binary mixture by the DW-spectrophotometry is studied, and that the application of the K-coefficient method and standard addition method proves to be more satisfactory. The regression equations for K-coefficient of manganese and zinc are established. The proposed method has been applied to the analysis of human hair with satisfactory results.
