Scholarcy highlights

  • The adsorption of U(VI) onto dried and pyrolyzed tea and coffee wastes was investigated
  • The adsorption properties of the materials were characterized by measuring uranium uptake as a function of solution pH, kinetics and adsorption isotherms. pH profile of uranium adsorption where UO22+ is expected to be the predominant species was measured between pH 0 and 4
  • Dried tea and coffee wastes proved to be effective adsorbents with high capacities and significant advantage of a very low cost
