摘  要：
采用臭氧水处理、乙腈萃取和气相色谱法(GC)分析,对采后马水桔果实中的有机磷农药降解效果进行研究,探讨臭氧水质量浓度、处理时间及处理温度等因素对臭氧降解有机磷农药效果的影响。结果表明:采后马水桔果实在温度为0℃、质量浓度为5mg/L的臭氧水中浸泡处理6min,有机磷农药的降解效果最好,30d后测得磷铵、治螟磷、甲基异柳磷和毒死蜱的降解率分别达到81%、81%、85%、82%,马水桔果实中的大部分农药残留得到降解清除。

摘  要：
The degradation characteristics of organophosphorus pesticide in Mashui orange by the advanced ozonation system were studied,with acetonitrile extraction and gas phase chromatography.The effects of ozone water concentration,temperature and handling time on the removal rate of organophosphorus pesticide were also investigated.The test results showed that there was the best degradation effect of organophosphorus pesticide residue when Mashui orange was soaked in ozone water of 0 ℃,5mg/L for 6min.After 30days,the degradation rate of ammonium phosphate,sulfotepp,isofenphos-methyl and chlorpyrifos was up to 81%,81%,85%and 82%,respectively,indicating that most organophosphorus pesticide residue was degraded.
