| 摘 要： | 采用火焰原子吸收光谱法对东江河沙中Na，K，Cu，Fe，Mg，Mn，Co，Zn 8种微量元素进行检测与分析。方法简单、快速、灵敏度高以及精密度好。算出回归方程和相关系数, 相关系数(r)均在0.994～1.000之间。选用HNO3-HF-H2O2混酸体系消化。结果表明，东江河沙中含有丰富的微量元素, 其含量由高到低顺序为Na>K>Fe>Mg>Mn>Zn>Co>Cu, 钠的含量最为丰富, 铜含量较少。实验结果为探讨东江河沙的保健作用提供了有用的依据。

| Abstract: | Eight kinds of microelements (Mn, Cu, Zn, Fe, Na, Co, Mg and K) in Dongjiang river sand were detected and analysed by flame atomic absorption spectrometry(FAAS). The method is simple and rapid with good precision and accuracy, and eliminates the interference effectively. The regression equation and the correlation coefficient were calculated. Correlation coefficients were 0.994-1.000. The samples were digested with HNO_3-HF-H_2O_2. The results showed that Dongjiang river sand contained abundant microelements. The content order is Na>K>Fe>Mg>Mn>Zn>Co>Cu with Na being the highest and Cu the lowest. This paper provides useful evidence for studying the health care effect of Dongjiang river sand on human body. |
