| Abstract | The adsorption properties of Leucaena leucocephala biomass to clean malachite green contaminated water wereinvestigated in this work. BET surface analysis showed a surface area of 0.5724 m?/g. Batch adsorption studies and isothermicstudies determined that the best time and temperature for the adsorption process to become efficient were 60 min of contact timeand 25 ?C, respectively. The KF value of 0.3372 mg adsorbed per mg of adsorbent of the L. leucocephala biomass for malachitegreen was the highest at 50 ?C. It was shown that the n values were n <1 which suggested that malachite green dye adsorption onL. leucocephala biomass is favorable. Values of the correlation coefficient (R2) indicated that the Freundlich isotherm can beused for the adsorption of malachite green on L. leucocephala. The results also suggest that L. leucocephala biomass can beutilized as an adsorbent for malachite green dye from wastewater at a lower cost. |
