The mechanism of separation of heavy metals from waters by means of cellulose carboxyl derivatives

Abstract

A mechanism of CS (Colloid – Sorption filtration) and CSF (Colloidal-Sorption – Filtration) separations are dynamic processes where, depending on intensity of media flowing in filter pores, also shear forces participate on trapping process of hydro-colloid particles. The adsorption capacity of cellulose carboxyl derivatives increases with increasing –COOH group content and is distinctly increased by the presence of other competitive ions in the aqueous solution.
