摘要:
建立了用离子色谱法测定有组织废气和无组织废气中丙酸的新方法,常规无机阴离子对该方法的测定没有干扰。对实际废气样品进行分析,丙酸的回收率分别为91.5%~106%。该方法分析速度快,所需样品量少,且无需要复杂的前处理,简便、灵敏、可靠。

Ion chromatographic determination of propionic acid in waste gas
Abstract:
A new method was established by using ion chromatography to detect the propionic acid in organized and inorganized waste gas while the conventional inorganic anions show no interference on the method. By analyzing the actual exhaust gas samples, the recoveries for propionic acid were 91.5% ~ 106%. The method has a convenient,sensitive,and reliable performance of quick speed, with a requirement of a small amount of sample, and no need of complicated pretreatment at the same time.
