摘要
痕量铝在硝酸介质中能催化加速过氧化氢和高碘酸钾与二甲苯胺兰FF之间的褪色反应。研究了反应的最佳实验条件,建立了测定痕量铝的新方法。方法检出限为6.1×10-10gAl3+/mL,检测范围为0-1.0μgAl3+/25mL。本方法具有高灵敏度,选择性较好,操作简便,快速的特点。用以测定水样中的痕量铝,获得满意结果。
A catalytic spectrophotometric method for the determination of trace aluminum has been established .It is based on the catalytic effect of aluminum on the oxidation of xylene cyanol FF by hydrogen peroxide and potassium periodate in nitric acid medium .The optimum conditions have been studied .The limit of detection is 6.1×10^(-10) g/mL aluminum .Aluminum can be determined accurately in the range of 0.0-1.0 μg Al^(3+)25 mL^(-1).The method has been applied to the determination of trace aluminum in environmental water with satisfactory results.
