Abstract
A method of producing hydrochar from jackfruit peel biomass includes hydrothermal carbonization of jackfruit peel biomass by autoclaving at 150° C.-250° C. for about 3 hours to produce a hydrochar. The hydrochar can be activated by treatment with phosphoric acid (HPO), hydrogen peroxide (HO), or a combination thereof. The hydrochar produced according to the method is particularly effective at removing azo-dyes, and specifically methylene blue, from aqueous solutions such as industrial waste water.
