Abstract— This paper presents results of analysis of the patent, scientific, and technical literature concerned with the physicochemical and technological foundations of the preparation of high-purity arsenic-containing compounds from various raw materials. Considerable attention is paid to processing of unconventional raw materials (lewisite detoxification products, nonferrous metals industry waste, and III–V semiconductor materials fabrication waste). Arsenic-containing substances (elemental arsenic, arsenic trichloride, arsenic trioxide, and arsine) containing less than 1 ppm by weight of regulated impurities have been prepared and characterized.
