Biosorption is characterized by the removal, retention, or recovery of metals present in toxic residues, through the adsorbent and adsorbate. For this, one of the characteristics to be evaluated in the determination of a good biosorbent is the zero-charge point. This value is defined by the pH value at which the biomass surface has a neutral charge, that is, the adsorption of H+ and OH- ions is equal. For the orange species studied, the values of the zero-charge point form between pH 4.5 and pH 5.8.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
