摘　　要：用原子吸收分光光度计测试了进口蕉,芝麻蕉,帝王蕉(小),帝王蕉(大)四个品种的香蕉中的钾的含量。样品采用微波消解,考察了电离干扰的情况,试验了加入抑制电离剂氯化铯的最佳含量。并考察了钾的最佳工作条件,在最佳条件下对其进行测试,并做了标准加入法。结果表明四个品种中的钾含量都相近都有2 500μg/mL左右。用微波消解方法可行,回收率都小于103%。The content of potassium in the import bananas,sesame bananas,the emperor bananas（small） and the emperor bananas（large） were tested by atomic absorption spectrometor（FAAS）.Samples were pretreated by microwave digestion,ionization interference,and the best content of cesium chloride was tested.The optimal working conditions of potassium was studied,which was examined under optimal working conditions.The results showed that the content of potassium in four species were closed,so microwave digestion method was feasible with the recovery less than 103%.
