The study was aimed at investigating the use of activated carbon prepared from Salvadora persica (ACSP) and the results were compared with the polyvinyl alcohol coated carbon prepared from Salvadora persica (PVAC-SP). Various factors affecting the adsorption process including solution pH, contact time, adsorbent dose and initial dye concentration were studied in a batch process. PVAC-SP was found to be most effective at pH 8. The kinetics of adsorption process was well described by the pseudo 2nd order kinetics model. The maximum adsorption of dye with ACSP and PVAC-SP were found to be 71.3% and 92.7% respectively.

Abstract


The study was aimed at investigating the use of activated carbon prepared from Salvadora persica (ACSP) and the results were compared with the polyvinyl alcohol coated carbon prepared from Salvadora persica (PVAC-SP). Various factors affecting the adsorption process including solution pH, contact time, adsorbent dose and initial dye concentration were studied in a batch process. PVAC-SP was found to be most effective at pH 8. The kinetics of adsorption process was well described by the pseudo 2nd order kinetics model. The maximum adsorption of dye with ACSP and PVAC-SP were found to be 71.3% and 92.7% respectively.
