Adsorption of Neutral Red by Pyrolytic Char from Pine Sawdust

Abstract:

Pyrolytic-char, a by-product from the slow pyrolysis of pine sawdust, was characterized by FTIR, SEM and XRD, etc. Then it was used as an adsorbent for the removal of cationic dye, neutral red (NR) from solution in batch mode. Adsorption studies were performed at different pH, salt concentration, contact time and dye concentration in the batch mode. Solution pH 6 is favor of adsorption and it is disadvantage of adsorption with common salt existed. Langmuir and Freundlich isotherm models were used to fit the experimental data and Freundlich was better. The adsorption quantity from experiment was up to 272 mg g¹ at 293 K. PR can effectively adsorb cationic dye from solution.
