dc.description.abstractRemoval of chromium (III) from aqueous solutions by leonardite (a low-cost adsorbent) was studied in a series of batch experiments. Stabilization of the adsorbent material with alginate beads was also investigated. The extent of adsorption was evaluated as a function of the solution pH, contact time, and the adsorbate concentration. Cr(III) removal was pH dependent, reaching a maximum at a pH range of 4–5. Kinetic studies allowed gives relevant information regarding mass transfer processes involved during the sorption process. Equilibrium data fitted well to both the Langmuir and Freundlich isotherm models and the maximum adsorption capacity turned out to be 75.2 mg Cr(III) g-1. Encapsulation of leonardite in alginate beads resulted in a slightly lower adsorption capacity.
