| 摘 要： | 在pH5.9的邻苯二甲酸氢钾－氢氧化钠缓冲体系中，在CTMAB的存在下，Fe(Ⅲ)和Al(Ⅲ)与BTAMoPACA形成最大吸收分别为670nm和690nm的有色络合物，吸收光谱严重重叠。采用双波长标准加入法对该混合显色体系进行研究，建立铁、铝同时测定的新方法，应用硅砖中痕量铁、铝的同时测定获得满意结果。

| Abstract: | Iron and aluminium can form colored complexes with a new reagent BTAMoPACA in weak acidic medium and in the presence of CTMAB. Their complexes have maximum absorbance at the wavelength 670 nm and 690 nm respectively, but their absorption spectra overlap each other seriously. A new method simultaneous determination of trace amounts of iron and aluminium without seperation is proposed with dual wavelength standard additions in this paper, and has been applied to the simultaneous determination of trace amounts of iron and aluminium in standard sample, the satisfactory results are obtained. |
