Dyes are usually present in trace quantities in the treated effluents of many industries. The effectiveness of adsorption for dye removal from wastewaters has made it an ideal alternative to other expensive treatment methods. This study investigates the potential use of untreated sugarcane bagasse and of untreated coconut husk for the removal of 10ppm methylene blue solution with time. At the end of the experiment, there will be selection on the best waste adsorbents based on the result of dye removal percent. Sugarcane bagasse and coconut husks were prepared at six periods which were 30min, 1 hour, 2 hour, 4 hour, 6 hour and 24 hour. Characterizations of the sugarcane bagasse and coconut husks have been conducted in order to understand the mechanisms involve to absorb the methylene blue. From FTIR spectra analysis, it suggests that adsorption happen through chemical complexation. SEM images proves that adsorption process occur, where it is proved by the obtained before and after the process. Based on the results obtained, it showed that untreated sugarcane bagasse has better adsorption ability, compare to coconut husk, and proves to be the most effective for biomass adsorbents in wastewater treatment industry.
