建立了用电感耦合等离子发射光谱法（ICP‐OES）测定聚氯化铝中的三氧化二铝的方法。分析谱线为Al309.217 nm ，铝的浓度在0.009 mg／L～100 mg／L范围内时，校准曲线的线性相关系数R大于0.9999，检出限为0.009mg／L ，方法的加标回收率在98％～102％之间，用该法对不同含量的聚氯化铝样品进行分析，测定结果与国标法测定结果基本相符。本方法简便、快速，适合聚氯化铝中三氧化二铝的测定。

A method for determination of aluminum oxide in poly aluminum chloride by inductively coupled plasma atomic emission spectrometry (ICP‐OES) was established. The analysitical line of Al was 309. 217nm .When the concentration of aluminum w as in the range of 0. 009 mg /L 100 mg /L ,the line‐ar correlation coefficient R of calibration curve was more than 0.9999 ,the detection limit was 0.009mg/L , the standard addition recoveries ranged from 98% to 102% .Poly aluminum chloride samples with differ‐ent contents were analyzed ,the results were basically consistent with national standard method. The meth‐od is simple ,fast and suitable for the determination of aluminum oxide in poly aluminum chloride .
