摘要
本文研究了用对甲基苯磺酸作为淋洗液测定液相中HCOO^-和CH_3COO^-的离子色谱条件,该方法对HCOO^-和CH_3COO^-的最低检出限分别为48ppb和93ppb。该方法与用进口的辛磺酸作为淋洗液的方法进行了对比实验,并用于两广实际酸雨样品中甲酸和乙酸的测量。
The conditions of ion chromatography using p-toluene sulfonic acid as eluant for the determinaion of HCOO^- and CH_3COO^- in acid rain were studied. The minumum detectable concentrations of HCOO^- and CH_3COO^- were about 48 ppb and 93 ppb respectively. Experiments compared with ion chromatography method using octane sulfonic acid as eluant were described, and this method was used to measure formic and acetic acids in acid rain at Guangdong and Guangxi province.
