Abstract
In this study, powdered boehmite (AlO(OH)) was compressed to obtain a granulated form without using a binder. The granulated product was assessed via SEM imagery, TG-DTA, specific surface area, surface pH, and hydroxyl groups. The SEM images showed that powdered BE could be successfully granulated by compression without binders. TG-DTA showed that dehydration of adhesion and bound water occurred at 96.0 and 394.6°C, respectively. The amount of phosphate adsorbed onto granulated boehmite increased with temperature, indicating a chemisorption mechanism. Moreover, equilibrium adsorption was reached within 20-24 h. Adsorption kinetics data was fitted to the pseudo-second-order model. [DOI: 10.1380/ejssnt.2012.518]
