Dye Waste Removal By Using Untreated Sugarcane Bagasse and Untreated Coconut Husk : A Comparative Study

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.
