【摘要】 <正> 前言感应耦合高频等离子体(ICP)作为一种优良的激发光源用于原子发射光谱多元素同时测定已在我国得到广泛的应用。但是,在选取测定条件时,人们往往采用简单比较法,即在多种影响测定的因子(参数)中,人为地固定其它因子的水平(参数的量值),只改变一个因子的水平,将所测到的信号值进行比较,选出一个“适当”的水平,如此逐更多还原

【Abstract】 In thispaper a simultaneous determination of Cu、Co、Ni、Ba、Zr、V、Be、Sr、La、Ce、Y、Yb and Sc in marine Mn-Fe nodules by Inductively coupled Plasma-Atomic Emission Spectroscopy are proposed. A Simple and effec-tive way to Select the promise Conditions are adopted, which is the simplified method for variance analysis in orthogonal expriments. The factors which have sighificant influence for the results of elements are discussed and identified.更多还原
