采样容器溶出氯离子对监测空气中氯化氢的干扰分析

The Disturbing Analysis of the Chlorin Ion from the Sampling Case to the Concentration of HCl in the Air

试验了玻璃、聚乙烯、聚四氟乙烯等不同材质容器溶出氯离子对环境空气中氯化氢测定的影响,指出测定结果偏高的原因在于采用玻璃气泡吸收管,分析了玻璃材质溶出氯离子的原因,建议采用特制的聚四氟乙烯或聚乙烯吸收管采样。

The interference experiments were performed in different material vessels such as glass, polyethylene, teflon to test dissolved chlorine ion for determination of the hydrogen chloride in ambient air. The test valves of air bubble sampling vessel increased because glass vessel released chlorine ion. The specially made teflon or polyethylene vessels were applied for air hydrogen chloride sampling.
