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和丙烯酸的新方法,常规无机阴离子对此没有干扰.对实际废气样品进行分析,丙酸、丙烯酸的回收率分别为91.2％ ～ 106％、92.0％ ～ 104％.该方法分析速度快,所需样品量少,且无需复杂的前处理过程,简便、灵敏、可靠.
The determination of propionic acid and acrylic acid in the organized and unorganized waste gas by ion chromatography,there was no interference between this new method of the determination and conventional inorganic anion.To analyse the actual gas samples,the propionic acid recovery rate was 91.2％-106％,and the acrylic acid recovery rate was 92.0％-104％.The advantages of this new method were high analysis speed,less sample required,and easy pretreatment.It is simple,sensitive and reliable.
