摘要
本文建立了王水-高氯酸硝解-ICP-OES测定重点行业企业周边环境样品中总磷的方法,所有一级国家标准物质的测试结果均在不确定度范围内,其RSD在0.06%~2.26%之间,该方法具有较好的准确度和精密度。同其他方法相比,该法测定范围广,测定范围为3.3mg/kg至100%,操作简单,不易污染,结果准确、可靠,适用于环境样品中总磷的测试。
In this paper,a method for the determination of total phosphorus in the surrounding environment samples of key industrial enterprises by aqua regia-perchloric acid nitration-ICP-OES was established.The test results of all first-class national standard materials were within the uncertainty range,and the RSD was between 0.06%-2.26%.This method has good accuracy and precision.Compared with other methods,this method has a wide range of determination,ranging from 3.3 mg/kg to 100%,which has the characteristics of simple operation,less pollution,accurate and reliable results,and is suitable for the determination of total phosphorus in environmental samples.
