Abstract

Wastewaters containing dyes are qualitatively dangerous and toxic. Researchers have, therefore, concentrated on simple and efficient methods for their treatment. The present study investigates the preparation of adsorbents from waste materials and evaluation of their performance in removing dyes from aqueous solutions. For this purpose, ACTIVATED CARBON is prepared from POMEGRANATE RESIDUALs by phosphoric acid (37%) activation and used to remove the REACTIVE BLUE 19 from aqueous solutions. Furthermore, the ACTIVATED CARBON thus obtained is characterized in terms of its morphological and textural properties, and the effects of such operation parameters as contact time, initial pH, adsorbent dose, and initial dye concentration on dye removal efficiency are evaluated.Results indicate the high surface area (SBET) of the pomegranate-based ACTIVATED CARBON (572.53 m2/g) and its maximum dye removal efficiency (98.16%) for a contact time of 5 minutes, at an initial pH of 11 with 3.5 gr/L of the adsorbent in an aqueous solution with an initial dye concentration of 300 mg/L. Finally, adsorption isotherm studies (Langmuir, Freundlich, and Temkin) and kinetic studies (the pseudo first-order, pseudo-secondorder, Elovich and intraparticle diffusion kinetic models) are performed to show that the ADSORPTION PROCESS follows a Langmuir isotherm equation (R2=0.955) and the pseudo-second order kinetic model (R2=0.997).
