| Abstract: | The method was established for determining lead,nickel,chromium,copper,iron,zinc,manganese,barium and cadmium in atmospheric particulates by ICP-AES with microwave digestion and perchloroethylene filter collection of the samples.The experimental conditions were optimized to produce the following results: good linearity,the detection limits of all elements from 0.001 mg/L to 0.01 mg/L,the RSDs of the filter samples from 0.6% to 2.9%,the recoveries from 96.0% to 105%. |
