不同的滤膜对PM2.5中测定铅元素的影响

Effects of Different Membrane for the Determination of Pb Element in PM2.5

不同的滤膜中铅元素的本底浓度都不且相同,且对于实验的稳定性也有所影响。本实验通过使用尼龙、石英纤维以及特氟龙等材质的滤膜,通过检测各种滤膜的本底浓度,以及检测PM2.5中铅元素的浓度,讨论不同的滤膜对PM2.5中铅元素的影响。

The background concentration of lead in different membrane elements is not identical, and also has influence on the experimental stability. Through the experiments of using the membrane, quartz fiber nylon and Teflon and other materials, through the detection of various membrane background concentrations, and the concentration of PM2.5 in the detection of Pb, discusses the influence of different membranes on the lead element in PM2.5.
