| Abstract | ||
| Using agriculture waste products waste Tea (WT) and activated carbon waste Tea (WT-GAC) as biosorbent for phenol from aqueous solution was studied. Adsorption in this way more economical in comparison with other conventional methods which are usually costly. Batch kinetics and isotherm studies were carried out under varying experimental conditions of contact time, phenol concentration, adsorbent dose and PH value. It was observed that the adsorption process is instantaneous and attained equilibrium within 10 minutes for activated carbon waste Tea and 30 minutes for waste Tea at phenol concentration (100-600) mg/L. the adsorption of phenol increase with increasing the solution pH value till pH 7 then it decrease with increasing pH value. The Freundlich and Langmuir models were used for the mathematical description of adsorption equilibrium and it was found that data fitted very well to the Freundlich models. | ||
