摘要
研究了微波消解样品,试液用ICP-AES法同时测定样品中K,Na,Ca,Mg,Fei Al,Ti,Zn,Cu,Pb,Cd,Cr,Co,Ni,As,P的新方法。方法的检出限分别为0.002～0.855μg/ml,回收率为90.17％-108.96％,RSD为1.32％～4.96％。该法准确、快速、简便,应用于花岗石的测定,结果满意。
The essay develops a new method of microwave degestion with a sample of ICP - AES simul-tanuously determining K, Na, Ca, Mg, Fe, Al, Ti, Zn, Cu, Pb, Cd, Cr, Co, Ni, As, and P. The limit of the method are 0. 002 - 0. 855μLg/mL respectively. The recoveries of the method are 90.17% -108.96% , RSD 1. 32% - 4. 96%. This method is accurate, quick - acquired and convenient. It is used in the determination of granite with the result is satisfactory.
