Анализ высокочистого оксида германия методом ИСП-АЭС и ДПТ-АЭС с концентрированием примесей в микроволновой печи

Abstract

The paper presents a vapor phase digestion and distillation of GeO[2] in the microwave accelerated reaction system Mars 5. In the frame of this work, the optimal conditions for closed vessels heating have been chosen. The germanium removals have been carried out in the form of volatile GeCl[4]. The germanium residual content in the solution after the distillation cycle has been determined by ICP-OES and MP-OES. To study the behavior of impurities during distillation the test called "introduced-found" has been conducted by the DCAOES method. The recovery of impurity elements was calculated in terms of the obtained data.
