摘要:針對供水行業(yè)高氯酸鹽、碘化物等指標檢測需求，開發(fā)了可在20 min內(nèi)檢測碘化物、草甘膦、高氯酸鹽、溴化物、氟化物、氯化物、硝酸鹽氮、硫酸鹽和磷酸鹽等9種化合物的淋洗液在線發(fā)生離子色譜方法。碘化物、草甘膦、高氯酸鹽、溴化物檢出限分別達到0.002、0.005、0.001、0.004 mg/L，其余5種化合物檢出限均滿足相關(guān)標準要求。在各指標定量限水平的平均加標回收率達到96.3%~104%，相對標準偏差為0.68%~3.79%。該方法簡單、靈敏度高，可實現(xiàn)對飲用水和水源水多指標的高效分析。應用該方法對南方某市水源水相關(guān)指標進行檢測的結(jié)果表明，碘化物和溴化物在水源水中普遍檢出，平均含量分別為0.028 mg/L和0.037 mg/L，個別水庫達到高碘水平；高氯酸鹽和草甘膦均未檢出；氟化物、氯化物、硝酸鹽氮、硫酸鹽等指標均滿足地表水Ⅱ類標準。對50個水廠出廠水水樣進行檢測，碘化物、高氯酸鹽、草甘膦、溴化物和磷酸鹽均未檢出，其他指標符合生活飲用水水質(zhì)要求。建議關(guān)注水廠供水工藝的碘代和溴代消毒副產(chǎn)物風險。
Abstract:To meet the requirements of perchlorate and iodide detection in water supply industry, an online generation ion chromatography method was developed for the detection of nine compounds such as iodide, glyphosate, perchlorate, bromide, fluoride, chloride, nitrate nitrogen, sulfate and phosphate in 20 min. The detection limits of iodide, glyphosate, perchlorate, bromide were 0.002 mg/L, 0.005 mg/L, 0.001 mg/L and 0.004 mg/L, respectively, and those of other five compounds met the requirements of relevant standards. At the quantitative limit level，the average recoveries were 96.3%-104% and the relative standard deviations were 0.68%-3.79%. The method is simple and sensitive, and can be applied to analyze drinking water and source water efficiently. The method was applied to detect the relevant indexes of source water in a city in south China. Iodide and bromide were widely detected in the source water with average concentrations of 0.028 mg/L and 0.037 mg/L, respectively, and high iodine concentration was detected in particular reservoir. Perchlorate and glyphosate were not detected. Fluoride, chloride, nitrate nitrogen, sulfate and other indicators met the limitations specified in surface water class Ⅱ standard. Water samples from 50 waterworks were tested. Iodide, perchlorate, glyphosate, bromide and phosphate were not detected, and other indicators met the requirements specified in drinking water quality standard. It is suggested to pay attention to the risk of iodine and bromine disinfection byproducts in water supply process.
