火焰原子吸收光谱法测定废气中铅
FAAS Determination of Lead in Waste Gas
摘 要
将空白滤筒用稀硝酸脱铅处理后,用于吸附废气.分别使用微波消解法、酸煮法和索氏提取法消解吸附了废气的滤筒,采用火焰原子吸收光谱法测定废气中铅含量.比较三种方法的回收率,试验选择微波消解法处理样品,铅的质量浓度与其吸光度在0.5~5.0 mg·L-1范围内呈线性关系,加标回收率在93.0%~96.2%之间.

Abstract
The blank filtering cartridge was rinsed with dil. HNO3 to eliminate lead ion,then used to absorb waste gas. The above filtering cartridge was digested by three different methods,including microwave assisted digestion,acid digestion method and Soxhlet extraction,and the solution obtained was determined by FAAS. Microwave digestion was chosen by comparing the values recovery of the 3 digestion methods. Linear relationship between the values of absorption and mass concentration of lead was kept in the range of 0.5-5.0 mg·L-1,with the values of recovery found by standard addition method in the range of 93.0%-96.2%.
