摘  要:
建立了HPLC-ICP-MS联用测定猪场废水中5种砷形态化合物的检测方法。将HAMILTON PRP-X100与CNW C18-WP色谱柱进行对比,优化色谱条件,以(2.5mmol/L柠檬酸+2.5mmol/L己烷磺酸钠pH4.5)+甲醇(99:1v/v)为流动相,在6min同时分析检测5种砷形态化合物。添加2~80μg/L浓度水平时,5种砷形态化合物添加回收率在87.6%~92.6%之间,相对标准偏差(RSD)在3.9%~5.6%之间,方法检出限(S/N=3)在0.3~0.8μg/L之间。结果表明:该方法前处理简单,灵敏度高,可用于日常监督检测工作。对了解规模化养猪场废水重金属砷污染状况,进一步开展规模化养猪污水对人类生活用水的污染提供数据基础。

摘  要:
An inspection method for determination of 5 arsenic compounds in piggery wastewater by HPLC-ICP-MS was established.HAMILTON PRP-X100 was compared to CNW C18-WP column and chromatographic conditions were optimized with(2.5 mmol/L citric acid+2.5 mmol/L sodium hexanesulfonate pH4.5)+ methanol(99:1 v/v)as the mobile phase.5 arsenic compounds were simultaneously determined at the 6 minutes.When the concentration was 2-80 mg/L,the recoveries of five arsenic compounds ranged from 87.6%to 92.6% with relative standard deviations(RSD)of 3.9%-5.6%.The detection limit(S/N=3)was between the 0.3-0.8 g/L.The method can be used for routine supervision and inspection with simplicity and high sensitivity.This paper contributes to the understanding of piggery wastewater arsenic pollution,which provides data basis for further large-scale piggery wastewater pollution on human life.
