摘    要:用离子色谱法测定环境空气中低浓度氯化氢,是通过测定氯离子质量浓度间接测定氯化氢的质量浓度,测定过程极易受外来氯离子的干扰,使空白值偏高。通过试验确定测定过程中可能存在氯离子干扰的环节,并采取一系列方法消除前期准备、采样和分析全过程中的干扰,以降低空白值。

关 键 词:氯化氢  干扰消除  离子色谱法  环境空气

Abstract:Hydrogen chloride in ambient air was determined indirectly by ion chromatography through the determination of chlorine ion. Because of the universal existence of chloride ion, the blank value was usually on the high side. Through the test, the possible links of existence of chloride ion interference were affirmed, and a series of methods were adopted to eliminate the interference in the whole process of preparation, sampling and analysis, so as to reduce the blank value.
Keywords:ydrogen chloride  Elimination of interference  Ion chromatography  Ambient air
