Acid hydrolysed Pine Sawdust as an Activated Carbon Low-Cost Substitute for Chromium(VI) Adsorption

D.K. Sidiras & D. Politi
Batch kinetics of Chromium (VI) adsorption on sulfuric acid treated pine sawdust was simulated, using untreated pine sawdust as control, in order to explore the potential use of this low-cost adsorbent for wastewater Chromium (VI) removal. A Severity Factor X was introduced to incorporate the effect of the pre-treatment time and the acid hydrolysis catalyst concentration on the pine sawdust adsorption properties. X is an explanatory variable for identifying biomass adsorption parameters as affected by...
