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.
