Toxic metals produced and released by the technological activities of humankind pose threat for the environment. The removal of chromate anions and zinc cations from dilute aqueous solutions by sorption was investigated in the present paper as typical examplles of toxic metals, existing in many wastewater streams. Seven inorganic materials have been examined as sorbents and compared, under similar conditions, using batch sorption experiments. Four of the sorbents were applied in powdered form (magnesite mineral - cosisting mainly from MgCO3-, titanium dioxide, hydrotalcite and goethite), while the other three were applied in granulated form activated carbon, ferric hydroxide and goethite, which was granulated by freezing/crystallization). Main examined parameters were the pH value of metal solutions and their intial concentrations. Due to the obtained results, goethite granulated by freezing/crystallization was selected for furthe (batch) sorption experiments, which were found to fit sufficient by the Langmuir isotherm equation.
