Abstract

This study is investigated the potential of sugarcane bagasse, an agriculture waste as adsorbent for the removal of methyl orange dye from aqueous solution. Numerous research had been done in preparing low cost adsorbent from agricultural by-products. Activated carbon undoubtedly is the most prevailing adsorbent because of its high surface area adsorption capacity, and degree of surface reactivity. The activation process during preparation of activated carbon is normally been performed at high temperature (i.e. higher than 500°C) and involved with a harsh chemical. This study investigated the potential of modified sugarcane bagasse with polyethylenimine (PEI) for removal of methyl orange (MO) dyes. The effect of PEI modified sugarcane bagasse adsorbent parameter on the efficiency of dyes removal including contact time, initial dye concentration, adsorbent dosage, temperature and pH have been investigated. The optimum result for MO dye removal achieve up to 82.0 % for parameters, contact time (240 min), initial dye concentration (0.01 g/L), adsorbent dosage (0.15 g/50 mL), temperature (30°C) and pH (7). The maximum percentage dye removal of MO dye was reached at contact time 240 min with percentage 82.78 % for 240 min and initial dye concentration 0.05 g/L at percentage 82.78 %. Based on the optimum result, the adsorbent was efficient in decolorised diluted solution. PEI modified sugarcane has high potential as low cost adsorbent for wastewater treatment containing dyes.
