摘要
用碳酸钠-碳酸氢钠混合液吸收大气中的乙酸盐,离子色谱法测定吸收液中的乙酸盐含量,根据采气量算出大气中乙酸盐含量。AC-检出限为0.060mg/L,当采气体积为100L时,最低检出浓度为0.006mg/m3,测定方法的相关系数r=0.9956,相对标准偏差<5%,样品回收率为93.6-95.8%。
In this method acetate in the air is absorbed with Na2CO3 - NaHCO3 and determined by ion chromatography. The detection limit of acetate was 0.006mg/m^3. The linear relative coefficient was 0.9956. The relative standard deviation for AC^- Was less than 5%, the recovery is 93.6 - 95.8%. The method is simple, rapid and the resalts were satisfactory.
