摘    要:钒具有生物活性,是人体所必需的微量元素之一。天然水中钒的含量很低,浓度大约为1-10μg/L。钒作为第一类污染物,上海市污水综合排放标准中对含钒污水的排放限值为2.0mg/L。文章探讨了用石墨炉原子吸收分光光度法测定水中钒的方法,具有灵敏度高、干扰少、重现性好、操作简便快捷、使用设备和试剂简单等优点。其方法检出限为0.002mg/L,RSD为1.4%,加标回收率在94.2%-103.0%,适用于地表水中痕量钒的测定。

关 键 词:  石墨炉原子吸收

Abstract:This article discusses the determination of vanadium in water by graphite furnace atomic absorption spectrophotom- etry method, which has the characteristics of high sensitivity, little interference, good reproducibility, easy operation and simple reagents. The detection limit was 0. 002 mg/L, the RSD was 1.4% and the recoveries ratio was from 94. 2% to 103.0%. It is applicable to determine vanadium in surface water.
Keywords:vanadium  graphite furnace atomic absorption spectrometry  water
