Optimized production, Pb(II) adsorption and characterization of alkali modified hydrochar from sugarcane bagasse

Abstract Today, sugarcane bagasse (SB) is used for bioethanol and biodiesel production, energy generation, and adsorbent synthesis. The goal of this project is to determine the optimized conditions for producing adsorbent from sugarcane bagasse using hydrothermal carbonization (HTC) and KOH activati...
