Аннотация
This paper reports results of studies aimed at developing physicochemical principles of the preparation of high-purity arsenic (99.9999 (6N) and 99.99999 wt % (7N) purity) from standard (As2S3 and As4S4 sulfide ores) and unconventional raw materials (lewisite disposal (detoxification) products, nonferrous metals industry waste, and III–V semiconductor fabrication waste). We present data on the behavior of impurities in arsine ultrapurification processes and substantiate integrated approaches to the preparation of high-purity arsine and arsenic from various raw materials.
