A modified computer spectrum-stripping method in ICP-AES with PDA or CCD as detector is developed for determining trace elements in multicomponents system of high concentration matrix without knowing concentrations of the matrix components.

• 本文使用固态检测器－光电二极管阵列（PDA）或电荷耦合器件（CCD）在ICP－AES上实现了无需知道基体浓度情况下对复杂组分中微量元素进行测定的计算机差谱改进法。
