Adsorption efficiency of coconut husk for removal of Rhodamine-B dye from aqueous solution
ABSTRACT The efficiency of acid modified locust bean pod (ALBP) as low cost adsorbent to remove Rhodamine-B (Rh-B) dye from aqueous solution was studied. The morphology, functional groups and elemental analysis of the adsorbent were investigated by SEM, FTIR, pH (pzc), and Boehm titration analytical techniques. Operational parameters such as contact time, initial dye concentration and solution temperature were investigated. The amount of Rh-B dye adsorbed was found to increase as these ...
