Effective Use of Biomass Wastes for Removing Hazardous Inorganic Ions from Aquatic Environment

Abstract

Trace concentrations of hazardous inorganic anionic species such as arsenate, phosphate, antimonite, selenite and fluoride can be effectively and selectively removed from water by means of adsorption using the gels prepared from biomass wastes such as orange juice residue loaded with multi-valent metal ions such as zirconium (IV). The adsorption capacities of these gels for arsenic are much higher than other adsorbents reported in literatures.
