发明了一种利用GASMET FTIR Dx4020便携式傅里叶红外分析仪测定水中挥发性有机物的实用方法,该方法可以定性定量25个水中挥发性有机物.该方法具有简便快捷、灵敏度高等特点,以苯系物中各单组分物质为例,方法检测限为11 ～45μg/L,相对标准偏差为3.4％ ～ 6.6％,加标回收率为98％ ～ 109％,在浓度范围内具有良好的线性.但对苯系物混合物定量准确性还需进一步研究提高.%A method to determine Volatile Organic Compounds (VOCs) in water with GasmetTM FTIR gas analyzers was provided, Testing 25 kinds of VOCs in water in qualitative and in quantitative. This method had characteristic features of quickness、simpleness and high sensitivity. Taking single component of benzene series for example,The detection limits were in range of 11-45 μg/L, and the recovery rates of benzene series were 98% -109% , and the relative standard deviations were 3. 4% -6. 6% with the good linear correlation. However, the testing mixture of benzene series precisely remains to be further studied.
