Abstract

The adsorption of methylene blue dye on the surface of diatomite was studied. Adsorption takes place due to the electrostatic interaction of dye cations and silanolic groups of diatomite. Investigation of the influence of pH on the adsorption efficiency showed that the amount of adsorption increased with pH increasing. The possibility of heterocoagulation associates dye and particles of diatomite in the system methylene blue – diatomite along with the adsorption processes was considered.
