ABSTRACT
Three Activated Kaza’s Carbons viz. NPTC, NLLC andNCC, are prepared from some Bio- Materials – Phaseolus trilobus, Leucena leucocephala and Casurina. These carbonsare used to adsorb dyes Methylene blue and Rhodamine B from aqueous solution. Adsorption equilibrium data and kinetic processes were studied. The Langmuir isotherm provides the best correlation for the experimental data, where as Temkin and Dubinin – Radushkevich (D-R) isotherms also fit to the experimental data. In the kinetic studies the best fit Model was assessed by the squared some of errors (SSE) values. Adsorption of dyes, Methylene Blue ( MB ) and Rhodamine B ( RB ) ,on to adsorbents could be described by pseudosecond order equation. The adsorption process has good co-ordinance with pore diffusion and Elovich equations.
