Leucaena leucocephala biomass treated with sodium dodecylbenzene sulfonate (SDBS) as an adsorbent for malachite green uptake from contaminated water

Abstract

Dyes are significant pollutant of our clean water. Adsorption using activated carbon uses lots of energy in the production stage. Thus, it is an expensive choice for contaminant clearance from wastewater. Modification of biomass particles using suitable chemical can produce adsorbent with lower cost. In this study, the Leucaena leucocephala biomass was treated with sodium dodecylbenzene sulfonate (SDBS) as an adsorbent for Malachite green uptake from contaminated water. Batch adsorption studies were done to study the effect of various parameters on the adsorption percentage of the prepared adsorbent. The results showed that the optimum values evaluated for each adsorption parameters are 20 ppm for initial adsorbate concentration, 60 minutes contact time, 30 C for solution temperature, pH of 7, adsorbent particle size of 0.425 - 0.5 mm and 0.5 g/L adsorbent dosage. The results showed that SDBS treated Leucaena leucocephala has the potential to be used as a low-cost adsorbent for Malachite green dye from contaminated water.
