Электролит для регенерации золота с покрытий относится к электрохимической обработке металлов, в частности к регенерации золота с отходов радиотехнической и электронной промышленности, Изобретение способствует повышению скорости растворения золотого покрытия, полноте его регенерации с основы и повышению устойчивости электролита. Для этого в электролит, содержащий роданистый калий и углекислый натрий, дополнительно вводят тиосульфат натрия и трехатомный спирт при следующем соотношении компонентов, г/л: роданистый калий - 20-600; углекислый натрий - 50-120; трехатомный спирт - 5-100; тиосульфат натрия - 1-15.The electrolyte for gold regeneration from coatings relates to the electrochemical processing of metals, in particular, to the regeneration of gold from radio electronic and electronic industry waste. To do this, sodium thiosulfate and triatomic alcohol are additionally introduced into the electrolyte containing rhodium potassium and sodium carbonate in the following ratio of components, g / l: potassium rodanide - 20-600; sodium carbonate - 50-120; triatomic alcohol - 5-100; sodium thiosulfate - 1-15.
