Abstract
Surface modification onto Salacca skin with sodium dodecyl sulfate (SDS) for enhancement adsorption capability toward methylene blue (MB) and batik’s wastewater has been conducted. Research was focused on the change of physicochemical character of adsorbent using gas sorption analyses and Fourier-Transform Infra-Red (FTIR) spectrophotometric analysis. Performance of modified Salacca skin for MB and batiks wastewater was evaluated in batch adsorption system for kinetics and optimization study. The results showed that surface modification is in favor for enhancement the adsorption of MB and batik’s wastewater. The presence of functional group on surface plays important role for the surface interaction to enhance adsorption capability. The equilibrium data of MB adsorption by batch system reveals that the adsorption kinetics obey pseudo-first order kinetics and the mechanism described the more intensive surface interaction by surfactant modification.
