根据尿中铍的测定方法，建立了饮用水中铍的直接石墨炉原子吸收光谱分析方法。采用磷钼酸铵和抗坏血酸作为基体改进剂。基质改进剂成功地消除了分析水中铍含量的水样中常见的化学干扰，以及通过明矾凝固去除铍的罐试验中遇到的干扰。该方法被证明是标准加入法的一种简单、准确和精确的替代方法。方法检出限为0.03 ug/L，线性校准范围为0-6 ug/L。包括21份参考文献、表格、图表。

A direct graphite furnace atomic absorption spectroscopy method for the analysis of beryllium in drinking water has been derived from a method for determining beryllium in urine. Ammonium phosphomolybdate and ascorbic acid were employed as matrix modifiers. The matrix modifiers successfully eliminated common chemical interferences in water samples analyzed for beryllium content, as well as interferences encountered during jar testing of beryllium removal by alum coagulation. The method proved to be a simple, accurate, and precise alternative to the method of standard additions. Method detection limit was 0.03 ug/L, with a linear calibration range of 0-6 ug/L.
