摘要：

A method of radioactivation analysis has been developed for the determination of Mn, Cu, Zn and Cd impurities in gallium arsenide. After irradiation, arsenic and gallium are separated by distillation and solvent extraction, then the impurity elements are determined by substoichiometric methods. Mn is extracted as tetraphenylarsonium permanganate into chloroform, and other elements as dithizonates in carbon tetrachloride under various conditions. The contents of Mn, Cu, Zn and Cd in a gallium arsenide crystal with a carrier concentration of 1.8·1016/cc were 0.004, 0.02, 0.006 and 0.04 ppm, respectively. © 1969 Akadémiai Kiadó.
