Abstract:
1. A method of adsorbing organic molecules, pollutants, or both, the method consisting essentially of: contacting date pits, removed from dates, with a phosphoric acid solution having a phosphoric acid concentration of from about 1% by weight to about 30% by weight, to form treated date pits; drying the treated date pits to form treated, dried date pits; calcining the treated, dried date pits under conditions to cause the treated, dried date pits to thermally decompose and form activated carbon; pulverizing and screening the activated carbon; impregnating the activated carbon with titanium dioxide, to form a photocatalyst; and adsorbing organic molecules, pollutants, or both, by contacting the organic molecules, pollutants, or both, with the photocatalyst.
