摘要
针对大气颗粒物滤膜样品现有的消解方法中存在的不足,就空白滤膜样品,对其消解条件(消解用酸的质量分数、样品浸泡时间、消解加热时间)进行了优化研究,选择了砷(As)、钡(Ba)、镉(Cd)、锰(Mn)、铅(Pb)等金属元素进行了详细探讨,建立了一种操作简便、准确、能同时测定多种金属元素的消解方法,并将该方法与电感耦合等离子体原子发射光谱法(ICP-AES)相结合,对TSP滤膜样品中的相关金属元素进行了分析测定,与国家标准方法进行了比对,结果令人满意.
Due to disadvantages in current digestion methods, digestion conditions for filter collection of atmospheric particles, such as acid concentration, soak time and pyrogenation time, were optimized, and a simple, accurate digestion method was established. The established method coupled with ICP-AES was used in determination of As, Ba, Cd, Mn and Pb in TSP samples with satisfactory result. The established method was proved to be consistent with national standard method.
