摘　　要：目的:比较干法灰化、湿法消解和微波消解3种前处理方法对虾粉中砷含量测定的影响。方法:分别用干法灰化、湿法消解和微波消解处理样品,原子荧光光度法进行测定。结果:干法灰化和湿法消解测定结果相接近,湿法消解结果稍偏低;微波消解测定结果与其他两种前处理方法的测定值明显偏离。3种方法的回收率都能满足相关要求。结论:在虾粉样品的消解方法上应优先选用干法灰化和湿法消解,同时在分析过程中应对相关处理方法进行多方面比对,以得到准确的检测结果。Objective:To compare the effects of three pretreatment methods,dry ashing,wet digestion and microwave digestion on the determination of arsenic content in shrimp meal.Method:The samples were treated with dry ashing,wet digestion and microwave digestion,and the samples were determined by atomic fluorescence photometry.Result:The results of dry ashing and wet digestion were similar,and the results of wet digestion were slightly lower.The results of microwave digestion were significantly different from those of the other two pretreatment methods.The recoveries of all three methods met the requirements.Conclusion:Dry ashing and wet digestion should be preferred in the digestion methods of shrimp meal samples,and the relevant treatment methods should be compared in many aspects during the analysis process to obtain accurate detection results.
