This method was developed for the determination of trace amounts of aluminum(III) in dialysis concentrates using atomic absorption spectrometry after coprecipitation with lanthanum phosphate. The analytical parameters that influenced the quantitative coprecipitation of analyte including amount of lanthanum, amount of phosfate, pH and duration time were optimized. The % recoveries of the analyte ion were in the range of 95-105 % with limit of detection (3s) of 0.5 µg l. Preconcentration factor was found as 1000 and Relative Standard Deviation (RSD) % value obtained from model solutions was 2.5% for 0.02 mg L. The accuracy of the method was evaluated with standard reference material (CWW-TMD Waste Water). The method was also applied to most concentrated acidic and basic dialysis concentrates with satisfactory results.
该方法是为使用原子吸收光谱法在与磷酸镧共沉淀后测定透析浓缩液中的痕量铝（III）而开发的。对影响分析物定量共沉淀的分析参数进行了优化，这些参数包括镧的用量、磷酸盐的用量、pH值和持续时间。分析物离子的回收率在95-105%范围内，检测限（3s）为0.5μg/L。预富集因子为1000，从模型溶液中获得的0.02mg/L的相对标准偏差（RSD）%值为2.5%。使用标准参考物质（CWW-TMD废水）评估了该方法的准确性。该方法还应用于大多数浓缩酸性和碱性透析浓缩液，结果令人满意。
