摘要： 为提高化验室人员检测水平，确保药剂检测结果的准确性和客观性，在实验室内开展对聚合氯化铝中Al₂O₃质
量分数、盐基度、水不溶物质量分数的检测，采用z 比分数法对数据进行分析。结果表明：Al₂O₃ 质量分数的|ZB| 值在
0.28～1.58，判定结果均为满意；盐基度的|ZB| 值在0.18～1.58，判定结果均为满意；水不溶物质量分数的|ZB| 在0.19～2.89。其中04 号参加者的|ZB| 值为2.89，存在一定问题，其他参加者均为满意。

Abstract: In order to improve the detection level of laboratory personnel and ensure the accuracy and objectivity of reagent
detection results, mass fractionof Al₂O₃, basicity and mass fraction of water insoluble substance in polyaluminium chloride was
detected in the laboratory. This paper analyzed the data with The z-score method. The results showed that the |ZB| of Al₂O₃ content
ranged from 0.28 to 1.58, and the results were satisfactory; the |ZB| of basicity ranged from 0.18 to 1.58, and the results were
satisfactory; the |ZB| of the mass fraction of water insoluble substance ranged from 0.19 to 2.89. The |ZB| of No.04 participant was
2.89, which had some problems. The other participants were satisfied.

Key words: polyaluminium chloride; Al₂O₃ mass fraction; basicity; mass fraction of water insoluble substance; capacity validation
