| 中文摘要 | 研究了采用性质不同的两种毛细柱对气相色谱法(GC)测定卤乙酸的影响.结果表明:1)HP-5柱比DB-1柱检出的卤乙酸多一种,且精密度较好;2)对卤乙酸的回收率均在标准规定范围以内,使用DB-1柱时更接近100%;3)使用DB-1或HP-5柱时,方法的检出限和定量下限均明显高于实际水体卤乙酸可能的浓度,可以满足实际检测的要求.; In this article, effects on detection of haloacetic acids using different capillary columns in GC analysis were studied and conclusions were as follows. The first, HP-5 column could detect one more haloacetic than DB-1 and its precision was better. The second, recoveries of haloacetic acids were all in the standard ranges and were approaching 100% when using DB-1 column. The third, the detection limits and quantitative lower limits were much higher than the possible HAAs concentrations in actual waters, and thus this method was able to satisfy the requirements of practical HAAs monitoring or detecting. |
