In Ukraine, the main sources of germanium, of interest for its industrial extraction is waste from processing iron ore and products of steam coal combustion. The most common method to determine the small quantities of germanium remains spectrophotometric determination by phenylfluorone, because of its high sensitivity and ease of implementation. Preparation and dissolution of samples of fly ash from coal-burning power used on the Dnieper HPP was carried out by GOST10175-75. The resulting solution was extracted with carbon tetrachloride.
