Abstract:

The novel synthesis route using the principle of green chemistry has been developed for biochar composite synthesis. The selection of feedstock was made on the basis of elemental composition of raw materials. The orange peel was modified with eggshell suspension which provided in-situ activation during pyrolysis. The characterization of the orange peel composite showed high porosity, rich in mineral content with large surface area. The application of the composite was used for the aqueous emerging contaminants Bisphenol A and the frequently used dye Methylene blue. As the majority of the adsorption studies are led with metal impregnated composites, so this study offered a green sustainable sorbent. The adsorption capacity for Methylene blue was 167mg/g and showed 100% removal rate with maximum adsorption capacity of 159mg/g. This methodology successfully achieved its goal of novel methodology and application for the removal of aqueous organic contaminants.
