中文摘要:
      采用固相萃取-GC-MS/MS法测定水中10种N-亚硝胺类化合物,通过试验优化前处理和测定条件,使方法在0.500 μg/L~100 μg/L范围内线性良好。方法检出限为0.6 ng/L~2.1 ng/L,混合标准溶液6次测定结果的RSD<5%。将该方法用于测定实际水样,结果除N-亚硝基二甲胺、N-亚硝基甲基乙基胺和N-亚硝基二丙胺以外,其余目标物均为未检出,加标回收率为73.1%~97.6%。
英文摘要:
      The solid phase extraction GC MS/MS method was used to determine 10 N nitrosamines in water. The pretreatment and determination conditions were optimized by experiments. The linearity of the method was good in the range of 0.500 μg/L to 100 μg/L. The method detection limits were 0.6 ng/L~2.1 ng/L,the RSD of 6 duplicate measurements for mixed standard solution was less than 5%. The method was applied in actual water samples. The results showed that all the target compounds were undetected except N nitroso dimethylamine, N nitroso methyl ethylamine and N nitroso dipropylamine. The recoveries were in range of 73.1%~97.6%.
