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 HNO3-HF-H2O2. 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.
