摘要: 目的 建立测定饮用水消毒副产物中可吸附有机氯(adsorbable organic chlorine,AOCl)、可吸附有机溴(adsorbable organic bromine,AOBr)和可吸附有机碘(adsorbable organic iodine,AOI)的方法。方法 活性炭吸附水中有机物,经过高温裂解转化为卤化氢并溶解于水,再以离子色谱法(ion chromatography,IC)测定AOCl,用电感耦合等离子体质谱法(inductively coupled plasma-mass spectrometry,ICP-MS)测定AOBr和AOI。结果 饮用水中AOCl、AOBr和AOI的线性范围分别为10~100、0.1~30.0和0.01~5.00 μg/L,线性相关系数(r)>0.99。AOCl、AOBr和AOI的检测限分别为2.5、0.02和0.002 μg/L,定量限分别为8.14、0.08和0.007 μg/L。加标回收率分别为87%~110%、79%~105%和92%~109%。结论 该方法操作简单、检出限低、精密度高、回收率高,适用于饮用水消毒副产物中AOCl、AOBr和AOI的定性、定量分析。

Abstract: Objective To establish a method for determining the levels of adsorbable organic chlorine(AOCl),adsorbable organic bromine(AOBr),and adsorbable organic iodine(AOI) in disinfection by-products of drinking water. Methods The organic substances in water were adsorbed by acti-vated carbon,then converted into hydrogen halides through high-temperature pyrolysis and dissolved in water,followed by the determination of AOCl using ion chromatography(IC),AOBr and AOI by inductively coupled plasma-mass spectrometry(ICP-MS). Results The linear ranges for AOCl,AOBr and AOI in drinking water were 10-100,0.1-30.0,and 0.01-5.00 μg/L,respectively,with linear correlation coefficients(r)>0.99.Detection limits were established at 2.5 μg/L for AOCl,0.02 μg/L for AOBr,and 0.002 μg/L for AOI,with quantitation limits correspondingly set at 8.14,0.08,and 0.007 μg/L.The spiked recovery rates were 87%-110%,79%-105%,and 92%-109%,respectively. Conclusion This method has operational simplicity,low detection limits,exceptional precision,and superior recovery performance,andis suitable for both qualitative and quantitative analysis of AOCl,AOBr and AOI in disinfection by-products of drinking water.
