摘  要：
以市售广西砂糖橘为材料,采用微波消解法处理样品,以电感耦合等离子体发射光谱仪(ICP-AES)检测砂糖橘中Cu、Fe、Zn、Mn、Na、K、Ca、Mg、P等14种矿质元素的含量,结果表明,砂糖橘果皮和果肉中K、Ca、Mg、P等元素的含量较高;果肉中K含量尤其高,达到9 082.23 ug/g,而Na含量则很低,果肉中仅含80.45ug/g,元素Cr在果皮和果肉中均未检出;Sr在果肉中未检出,在果皮中含量为10.24ug/g;在砂糖橘果皮中B、Ca、Mg、Fe、Mn、Si、Zn 7种元素含量均高于果肉。加标回收率实验表明,各元素的相对标准偏差(RSD)为0.18%~4.77%,各元素的回收率在95.15%~106.1%之间,说明该方法测定广西砂糖橘中矿质元素具有较好的精密度和准确度。

摘  要：
The contents of 14 elements such as Cu,Fe,Zn,Mn,Na,K,Ca,Mg and P were studied by ICPAES with microwave digestion in Citrus reticulata Blanco cv.‘shiyueju',and the results showed that,the contents of K,Ca,Mg,P were higher inpeel and pulp. The content of K in the pulp were very high,reached 9 082. 23 ug / g,while the content of Na were very low,with only 80. 45 ug / g. The Cr elements were not detected in fruit peel and pulp. Sr was not detected in the flesh,but its content was 10. 24 ug / g in the peel. The content of B,Ca,Mg,Fe,Mn,Si,Zn in peel were higher than that in the flesh. The relative standard deviations and recoveries of all elements determined with ICP-AES were between 0. 18% ~ 4. 77% and 95. 15% ~ 106. 1% respectively. The combination of microwave digestion with the ICP-AES showed that this technolgy has better precision and accuracy.
