| Abstract: | Objective] To establish a method of determination of calcium,copper in kiwi fruits by microwave digestion-flame atomic absorption spectrometry.Method] The sample was diluted by microwave with HNO3 and the contents were determined by calibration curve method.By performing a series of experiments on the parameters of digestion conditions and atomic absorption of samples,the optimal parameters of digestion conditions and atomic absorption were determined.Result] The results of determination showed that the copper content in Jinyan,Hongyang and Jinguo were 0.058,0.076 and 0.063 mg/g,respectively,and the calcium content were 1.812,1.530 and 1.539 mg/g separately.Recoveries are 94％-106％ and RSD are 3.3％-4.7％.Conclusion] The method is feasible and the result is accurate,which can be used for determining copper and calcium content in kiwi fruits. |
