摘要
本文讨论了一种利用双波长标准加入法测定双组分系统的新的分析方法。通过对λ_1和λ_2组合的适当选择,掩蔽干扰物而用标准加入法测定分析物。用本方法测定铬和锰的混合物和样品获得令人满意的结果。
A new analytical method for the determination of two component system by means of a dual-wavelength standard addition method is described. By proper selection of the combination of two wavelength λ1 and λ2,the interferent masked and the analytical component are measured with the standard additon method. By this method ,Cr and Mn in the mixture and in the steel sample were determined with satisfactory results.
