摘要
大气飘尘(颗粒物)是大气污染监测的主要项目之一(废气和尘土)。其中含有多种痕量重金属元素(如镉、钒、铬和铍等)随着人的呼吸进入体内,有致癌作用;或可引起高血压、动脉硬化、心脏病和肺纤维硬化等疾病。因此,飘尘中痕量重金属元素的含量,已成为评价大气质量、研究大气污染对人体健康的影响、以及研究飘尘颗粒物中重金属元素分布规律的一个重要科学依据。根据飘尘分析样品量少、待测元素多含量痕的特点。本文采用广为应用的多元素同时测定、检测能力强。
The effects of some carriers on the raise of the sensitivity and precision of the spectrochimical analysis were investigated The result show that the effect of mixed carrier is better than individual one, and LiCl-KH_2PO_4 is best. The influence of matrix composition was examined. A simple and practical method for the determination of Pb、Cr、Ni、Cu、Be、V Fe and Zn in airborne particulate metters by AES is established. The RSD is smaller than 7.8%,whereas the recoveryis 86.6—113%.
