Investigation of performance of a non hydrolyzed polymer for removing of some dyes from wastewater

In this study, a non hydrolyzed polymer has been used as a new synthetic adsorbent for removal of Eosin B and acid red 14 dyes from aqueous solutions in industrial wastewaters. Study of the effect of certain parameters like agitation time, pH, adsorbent dose, initial concentration and temperature, etc., on dyes removal efficiency were investigated. Equilibrium data were fitted with Langmuir and Freundlich isotherms to find the best fit and it was found that the adsorption of these dyes on adsorbents particles are mono layer and correspond to the Langmuir isotherm. Adsorption kinetic data were investigated using pseudo first order and pseudo second order rate equations and kinetic data followed the pseudo second order rate equation for sorption of these dye on the adsorbent. This study provides good background to development of dyes removal in wastewaters by polymeric sorbent.
