Abstract

Synthetically prepared simulated waste waters was used for exploring sorption abilities of the sorbent substance obtained from barks and leaves of Pomegranate towards Methyl Red. Factors that affect adsorption like temperature, adsorbent dosage, starting dye concentration and time of contact were evaluated. Four adsorption isotherms namely Freundlich, Langmuir, Temkin and DubininRadushkevich were analyzed for studying equilibrium of adsorption. Rate and adsorption process kinetics were identified by applying Weber and Morrish intraparticle diffusion, Bangham’s pore diffusion, pseudo-first-order, pseudosecond-order and Elovich equations. Fivefold excess of common ions interference in natural aquifers, have been analyzed. Cations such as Ca2+, Mg2+ and Cu2+ have shown little interference but Fe2+ and Zn2+ions combinedly maintained maximum withdrawal of the dye. Procedures that were developed could be successfully applied to few industrial effluents. Data collected out of experimentation was suitable to the pseudo-First order kinetic standard. Correlation coefficient (R2) and dimensionless separation factor (RL) values conformed that adsorption process follows Langmuir adsorption indicating single layer formation. The adsorption process had good correlation coefficient equivalence with pseudo-second-order model. Temperature effect was also studied.
