Removal of Phosphates from Water Using Eggshell BioSorbents

Anastasija Smirnova, Daina Kalniņa, Jānis Ločs

The present study focuses on the preparation and use of biosorbents produced from eggshells. Hen eggshells are produced as a by-product in large quantities by food manufacturers. The adsorption efficiency of phosphate ions from the obtained biosorbents - raw eggshell powders - is studied at room temperature in static conditions. The effect of phosphate concentration and sorbent mass on the efficiency of the process is evaluated, as well as sorption kinetics is investigated. The structure, phase composition, porosity, specific surface area and morphology of the obtained biosorbents are determined. The utilization of eggshells as an abundant, cheap and biodegradable material for the removal of phosphates is studied and discussed.
