摘要: 研究了Al(Fe)-CAS、Al(Fe)-CAB在不同增溶体系中的双波长光度行为,提出了双波长等吸收法中“非零等吸收点”的可用性,并在铝铁同时测定中得到验证。

Abstract: In this paper the photometric behavior of Al(Fe)-CAB,Al(Fe)-CASin the presence of mixed surfactants and the feasibility of non-zero isosbestic point in the double-wavelength spectrophotometry have been studied.The present method is successfully applied to the simultaneous determination of Al and Fe.
