Sorption purification of galvanic wastewater from Iron (Iii), Copper (Ii), Chromium (Vi) And Zinc (Ii) Ions Using Modified Solid Products of Pyrolysis Of Carbon-Containing Waste.

Abstract

The adsorptive ability of products of pyrolysis on methylene blue is investigated on the spectrophotometer UNICO 2800. The product of pyrolysis of sludge sediments showed sorption properties to ions of heavy metals, with respect to iron ions, the degree of sorption was 99.8%, for the remaining investigated heavy metal ions it ranged from 35.4 to 77.6%. To increase the sorption activity of pyrolysis products, their activation by acid and alkali solutions has been studied. It is determined that the alkali solution increases the sorption efficiency of pyrolysis products to a greater extent.
