| Abstract | ||
| This research involves the study of effect nature of the adsorbent in term of surface and volume of pores and the nature of the surface and the adsorbent ,the results showed that the efficiency of adsorption of Benzidin adsorbent followed the following sequence: Activated Carbon > Silica- gel > Alumina > Kaolin This research is also showed that activated carbon is better adsorbent compared with other adsorbents . The equilibrium time of adsorption was found (50-60)minute.Also the adsorption isotherm according to Freundlich and Langmuir equations is calculated , Thermodynamic properties (∆Go,∆Ho,∆So)are calculated and found the adsorption processes are Exothermic .The effect of changing the acidity of solution is also studied and found that as acidity increased the amount of adsorbate increased as well as effect of hydrogen bonding was discussed . | ||
