Potential application of propionic acid modified sugarcane bagasse for removal of basic and acid dyes from industrial wastewater
Factors affecting the use of cheap and ecofriendly pretreated bagasse for potential removal of methylene blue (basic dye) and orange II (acid dye) from wastewater were studied. Sugarcane bagasse was pretreated with propionic acid with the aim to effectively adsorb the above mentioned two dyes at varying dye concentrations, adsorbent dosage, pH and contact time. The kinetics of dye sorption processes fit a pseudo-second-order for methylene blue and pseudo-first-order for orange II kinetic models. Adsorption isotherms fit well into the Langmiur equation, where the maximum sorption capacities are 59. 9 and 26.7 mg/g for methylene blue and orange II, respectively.
