Abstract

Изобретение позволяет обрабатывать удаляемый шлам после гальванической обработки металлов и, в частности, возвращать для повторного использования отработанные травильные кислоты после травления. Предложен экологически чистый способ, который дает кислоты для повторного использования и чистые пигменты железа наноразмеров как побочный продукт.
