海底沉积物用硝酸-高氯酸-氢氟酸消解,然后用ICP-AES法同时测定常量和微量元素。研究了样品中基体元素对微量元素测定的光谱干扰,并采用干扰曲线斜率法进行干扰校正,分析批量海底沉积物样品获得满意结果。
Sea sediments with nitric acid - perchloric acid - hydrofluoric acid digestion, and then by ICP-AES method for simultaneous determination of trace elements and trace elements. The spectral interferences of the matrix elements in the samples for the determination of trace elements were studied. Interference curves were also used to correct the interferences. The results of mass sediment samples were obtained.
