In the context of the growing need for environmentally friendly and effective methods of water purification, the attention of researchers is attracted by natural sorbents. In this paper, the sorption properties of persimmon (Diospyros kaki) seeds are investigated as a potential biosorbent for removing pollutants from aqueous solutions. Experiments were conducted to determine the adsorption efficiency of heavy metals (e.g. lead and copper) and organic substances (e.g. phenol). Adsorption parameters such as capacity, kinetics and isotherms were estimated. The results showed that crushed and activated persimmon seeds have high sorption capacity, especially in an acidic environment. Thus, persimmon seeds are a promising, cheap and environmentally friendly material for creating new generation biofilters.
