Анализ кадмия и его оксида методом атомно-эмиссионной и масс-спектрометрии с индуктивно связанной плазмой

Abstract

In present work, the multielemental methods for the cadmium and its oxide analysis by atomicemission and mass-spectrometry with inductively coupled plasma (AES-ICP and MS-ICP) have been proposed. The influence of the matrix concentration and the power supplied to the plasma on the analytic signals of the impurities has been studied, analytical lines and isotopes of the determined elements have been chosen. We have made the accuracy estimation of the developed techniques, the ICP-AES technique allows to determine 41 analytes with detection limits in the range from n•10{-7} to n•10{-4} % wt, ICP-MS technique allows to determine 58 elements with detection limits on the level n •10{-8}-n•10{-3} % wt Введение. Кадмий высокой чистоты является прекурсором.
