In this work, adsorption of Rhodamine 6G, Carmine, Fast Green FCF,Safranine O from aqueous solution onto activated charcoal were prepared from Bamboo seed seed by physicochemistry activation with potassium hydroxide (KOH) as the activated agent at 700°C for 1hour and particle size 600µm analyzed results by U.V-Visible technique .The influence of variables parameters including PH, amount of adsorbent, sieve size of adsorbent, temperature and contact time on dyes removal were studied. The isotherm data was analyzed by Langmuir, Freundlich, Tempkin,Harkins-Jura and Dubinin-Radushkevich. Calculation of various thermodynamic parameters such as enthalpy (∆H), entropy (∆S), Gibb’s free energy changed (∆G), activation energy (Ea), sticking probability (S*). The positive values of (∆G) indicate that the dyes adsorption process is unspontaneous in nature and the negative values of (∆H) shows the exothermic nature of the process. The adsorption kinetics shows that, pseudo first order and pseudo second order rate equation, pseudo second order was fitted better than pseudo first order.
