| 摘 要： | 通过酸消解,原子荧光-氢化物发生法测定了广州市26种市售水果中硒的含量,由标准物质(GBW08551猪肝)和回收率控制检测质量。结果表明,不同水果中硒含量有较大差异,含量范围为1.03～13.2μg/kg,平均含量为4.97μg/kg,不同类型水果中硒含量变化特征是:热带亚热带水果(6.03±2.59μg/kg)>浆果类(5.53±0.87μg/kg)>仁果类(5.18±0.33μg/kg)>核果类(4.78±0.97μg/kg)>柑橘类(3.92±0.50μg/kg)>瓜果类(3.43±0.94μg/kg)。

| Abstract: | Selenium contents in various fruits from the Guangzhou city, Guangdong province, were determined after acid digestion by hydride generation atomic fluorescent spectrometry. All fruits were sampled from supermarkets and terminal markets. Accuracy was assured with standard reference material (GBW08551) and recovery rate in experiments. A wide range of selenium content (1.09～13.3μg/kg) is found among the various fruits, and the mean selenium content in fruit is 4.97μg/kg. The selenium content of various fruit groups is in the order: tropic fruit (6.03±2.59μg/kg)>berry (5.53±0.87μg/kg)>kernal fruit (5.18±0.33μg/kg)>drupe fruit (4.78±0.97μg/kg)>orange fruit (3.92±0.50μg/kg)>melons (3.43±0.94μg/kg). |
