扩散法测定环境空气中的二氧化硫

介绍了利用自制分子扩散式个体采样器 ,监测环境空气中的二氧化硫的方法 ,该方法改 PRA光度法为离子色谱法 ,提高了方法的灵敏度。经实验室性能评价能够满足实验室测试的要求。并经有动力的溶液吸收管法现场对比测试 ,两种测试方法结果一致

Measuring SO2 in Ambient Air by Diffusion Sampler

Measuring SO2 in ambient air by molecule diffusion sampler is introduced in this article. Iron chro-matographer instead of traditional PRA spectrophotometer analyzes the sample in the method, so the sensitivity is in-creased. Through experimental assessment,this method can reach the requirement of experimental measurement. In addi-tion ,compared with the positive method of absorb－tube in sites ,the results correlate well.
