| 摘 要： | 对饮用水源水中丙烯醛的气相色谱标准测定方法作了改进,由直接进样改为吹扫捕集进样,由极性色谱柱改为中等极性色谱柱.方法在0.010 mg/L～0.100 mg/L范围内线性良好,最低检出限和检测下限分别为0.000 5 mg/L和0.002 mg/L,水样平行测定的RSD为2.8%～5.2%,平均加标回收率为90.0%～...

| Abstract: | There had been some improvements for standard method to detect acrolein in drinking water sources.Sampling mode had been changed from direct injection into the purge and trap.GC column was replaced from polarity to medium polarity.Results showed that good linearity of method obtained in range from 0.010 mg/L to 0.100 mg/L,lower limit of detection 0.000 5 mg/L,detection limits 0.002 mg/L,RSDs of parallel samples between 2.8% and 5.2%,average spiked recoveries between 90.0% and 100%.Each technical parameters ... |
