The migration of ions of heavy metals (Zn 2+ , Cu 2+ , Cr 3+ , Cr 6+ , Ni 2+ , Fe 2+ and Fe 3+ ) from ceramic bricks containing wastewater sludge from electroplating industries. The regularities of the migration of chemical elements under the influence of various factors (temperature and exposure time, pH of the model medium) in relation to the charge and chemical composition of the masses, as well as the structure and phase composition of materials have been established. The optimal content of sewage sludge in the composition of the masses for obtaining ceramic bricks, which fully meets the requirements of regulatory documents for the migration of chemical elements, has been determined.
