摘要
环境中挥发性有机污染物(VOC)的存在很复杂,随着VOC治理技术的进步,环境水中VOC浓度有不断降低的趋势,要求VOC分析具有更低的检测限。通过对环境水前处理过程采用优化吹扫捕集条件来扩大试样量、选择高灵敏度的检测器以及降低前处理过程的空白值、提纯分析用水;优化VOC色谱分离条件,确保色谱峰良好分离来降低试样和空白值的标准偏差的研究。
VOC in environment is very complicated and is decreasing with the development of VOC control, which demands lower detection limits of VOC. With larger volume of samply by optimized conditions, more sensitive detector, lower background noise, purified analytical water, optimized chromatographic condition, detection limits were lowered.
