在PH─6．0的醋酸─醋酸钠介质中，以铬天菁S─十六烷基三甲基溴化胺做混合指示剂，光度法测定人发中微量铝的方法。检出限0．365μg／25ml，线性范围：0．5～6．0μg／25ml，加标回收率：95％～104％铝含量在4．0μg／25ml和6．0μg／25ml时，经11次测定其变异系数分别为3．22％和2．32％，结果满意。
In PH ─ 6.0 acetic acid ─ sodium acetate medium, with chrysanthemum S ─ ─ cetyl trimethyl ammonium bromide as a mixed indicator, a method for the determination of trace aluminum in human hair. The detection limit of 0.365μg / 25ml, linear range: 0.5 ~ 6.0μg / 25ml, spike recovery: 95% ~ 104% aluminum content 4.0μg / 25ml and 6.0μg / 25ml, the 11 The coefficient of variation was 3.22% and 2.32%, respectively, with satisfactory results.
