| Abstract | ||
| This work involves the study of adsorption of p-chlorophenol (PCP) from aqueous solution on the activated carbon of filter used in drinking water purification units ,which prepared from coconut shells .The adsorption studied at different PCP concentrations and different temperature spectrophotometrically . The value of adsorbed quantity (Qe) was measured for each concentration at equilibrium (Ce) and the percentage of adsorbed quantity (Qe%) was also calculated . The results show that the percentage of adsorbed quantity increased as the percentage of adsorbed quantity and increased as the concentration of PCP increases until the equilibrium condition obtained and also the value of (Qe%) is directly proportional to temperature . The isotherm of Langmuir , Freundlich and Temkin were tested and found that the results fits Freundlich isotherm better than Langmuir isotherm , while Temkin isotherm fit at 333k compared with other isotherms . The thermodynamic parameters (∆G , ∆H and ∆S) were also calculated and show that the adsorption is endothermic and spontaneous process and increased as the temperature increases , the entropy of adsorption was also increased with temperature | ||
