A novel method for the determination of chromium in biological samples based on the oxidation of chromogenic (Ⅵ) chromium (Ⅵ) with diamyipinin o-isopropoxyphenylmethane (DAOIM) was developed. The method has high sensitivity and good stability and is suitable for Determination of chromium in several biological samples with satisfactory results. Experimental part 1 instruments and reagents 722 spectrophotometer, 1cm cuvette; chromium (Ⅵ) standard solution: 1 0μg / ml?
