| 摘 要： | 利用原子吸收分光光度法分析了不同海水浓度灌溉不同年份采摘的菊芋中多种微量元素的含量。方法灵敏度高，精密度好，相关系数(r)在0.997 1～0.999 7之间。实验中比较其差异性，结果表明：菊芋是典型的高钾低钠食品，其含量K＞Mg＞Na＞Fe＞Ni＞Zn＞Cu＞Mn＞Cd，Pb，Cr含量极少。不同年份和不同海水浓度对其有一定的影响。此法有一定应用价值。

| Abstract: | The present study was carried out on the determination of trace elements in J.A by AAS,which has been irrigated by various concentrations of seawater and harvested in different years.The method is rapid with good precision and accuracy. Correlation coefficients were 0.997 1-0.999 7.The result suggests that J.A is rich in K,Mg and Na,specially the ratio of K to Na is very high,and the content order is K>Mg>Na>Fe>Ni>Zn>Cu>Mn with Pb,Cr and Cd being lower.In addition,some trace elements are different in various J.A.So the authors conclude that the concentration of seawater has effect on trace elements.Perhaps the method is worth much more utilization. |
