采用微波消解-电感耦合等离子体发射光谱法测定苹果干制品中铅、镉、砷的含量。经试验优化而确定的微波消化条件为加入2 mL浓硝酸，电热板温度86℃，预消化30 min，放冷至室温后加入1 mL双氧水，盖好盖子，装好罐，微波消化，定容后用ICP-AES检测。经分析，该方法回收率好，为93％~104％。从测定的结果可看出，苹果干制品中重金属含量为Pb<0.2 mg/kg，Cd<0.1 mg/kg，As<0.2 mg/kg，为苹果干制品产品标准的制定提供依据。
採用微波消解-電感耦閤等離子體髮射光譜法測定蘋果榦製品中鉛、鎘、砷的含量。經試驗優化而確定的微波消化條件為加入2 mL濃硝痠，電熱闆溫度86℃，預消化30 min，放冷至室溫後加入1 mL雙氧水，蓋好蓋子，裝好罐，微波消化，定容後用ICP-AES檢測。經分析，該方法迴收率好，為93％~104％。從測定的結果可看齣，蘋果榦製品中重金屬含量為Pb<0.2 mg/kg，Cd<0.1 mg/kg，As<0.2 mg/kg，為蘋果榦製品產品標準的製定提供依據。

The lead,arsenic and cadmium contents of the unfried dry apple are tested through microwave digestion and ICP-AES. The microwave digestion condition is add 2 mL nitric acid,86 ℃,30 min heating up on pyrogenation board,and then leave it alone,cooling to the room temperature. After that,add 1 mL hydrogen peroxide,then covering and packing, and then digest by microwave. After putting it to the constant volume,the ICP-AES is used to test the sample. It shows that the recovery rate of the microwave digestion is high,which is between 93% and 104%. It can be seen from the results that the content of Pb in the product is less than 0.2 mg/kg,Cd is less than 0.1 mg/kg,As is less than 0.2 mg/kg,which provides a basis for the establishment of unfried dry apple product standard.
