Abstract
In present study raw coconut frond was used as adsorbent in the removal of methylene blue dye. Adsorption using raw agricultural waste has proved to be more economical compared to other removal methods of dyes as the method of production is relatively easy. The optimum conditions for the removal of methylene blue using raw coconut frond were obtained at 0.125 mm of adsorbent size with 0.5 g adsorbent dosage at 24 h contact time. Initial dye concentration was found to work efficiently at 50 mg/L and pH 8. Adsorption isotherms were studied to understand the mechanism of dye adsorption. The experimental values obtained fitted well in the Langmuir isotherm. Maximum adsorption capacity is 18.69 mg/g with R2 = 1, suggesting a monolayer adsorption mechanism. The obtained results indicate that raw coconut frond has potential in removing methylene blue.
