摘要
在铁试剂（7－碘－羟基喹啉-5-磺酸，即Ferron）、溴化十六烷基吡啶（CPB）存在下，于pH4．3的乙酸-乙酸铵介质中，铝、铁分别生成Al－Ferron－CPB、Fe－Ferron－CPB三元络合物，采用双波长分光光度法，选测量波长390．0nm，参比波长445.1nm波长组合测定铝，单波长630mn测定铁，用此方法测定硅铁中的铁和铝，结果比较满意。
A method of dual-wavelength spectrophotomentry is applied to determination of Al and Fe inferrosilion. The measuring wavelength and referential wavelength are 390. 0 nm and 445. 1 nm for Al630. 0 nm for Fe. The respective relative deviation is 0. 011 and 0. 023, the coeffcient is 1. 30% and 0. 40%for Al and Fe. The method is repid, simple with satisfactory results.
