摘要
本文用流动注射,氢化物发生-ICP-AES检测体系对小麦粉、煤灰和土壤等样品中痕量的砷的进行检测,采用正交设计试验找出仪器测定的最佳工作条件,并对影响测定的主要参数和砷的氢化物产生条件进行了研究。该方法对试样中砷的检测结果令人满意,砷检测限为0.15μg/L,相对标准偏差<2.5%。
The detemination of trace arsenic in wheats ash of coal and soil etc. by a flow injection system involving hydride generation was associated with ICP-AES. The text have adopted orthogonal table Find out optimized terms of apparatus and primary parameters that have great influences on the determination and the conditions of hydrides formed. The method was used to determine trace arsenic with satisfactory results. The detection limits are 0.15% and relative standard deviation is less 2. 5%.
