Powdered waste sludge from the production of technical stone (TSW), produced by theTechniStone® Company (Hradec Kralove, Czech Republic), was surface modified withFe2+ and Mn2+ inorganic salts and then testified as a potential adsorbent ofenvironmentally important oxyanions (phosphate PO43-, arsenate AsO43- and chromateCrO42-) from contaminated waters. The surface modification in principle consisted increating a thin layer of hydrated Fe/Mn ions in reactive form on the TSW surface.Thanks to the change of the surfa...
