顺序扫描ICP-AES法测定海洋沉积物中九种主要成分

DETERMINATION OF MAJOR CONSTITUENTS OF MARINE SEDIMENT WITH INDUCTIVELY COUPLED PLASMA ATOMIC EMISSION SPECTROMETRY

用ICP—AES法测定海洋沉积物中铝、铁、钙、镁、钠、钾、钦、锰、磷等九种主要成分，方法简便，省时省力，测量精密度小于4％，可以满足海洋地球化学的要求。

A rapid, simple and accurte method for the determination of the xnajor constituents of marine sediment is described.The marine sediment samples were decomposed by HNO-HF-HCIO and the major e1ements of marine sediment Al, Fe, Ca, Mg, Na, K, Mn and P were determined by a computer controlled scanning monochromator with an inductively coupled plasma atomic emission spectrometer. The precision and accuracy of the method are satisfactory. The relative standard dexriation of the method is less than 4%.
