Possibility of Modification of Zeolites by Iron Oxides and its Utilization for Removal of Pb(II) from Water Solutions

Autor: Michal Lovás, Slavomír Hredzák, Miroslava Václavíková, Marek Matik, Štefan Jakabský

Publikováno v: Acta Montanistica Slovaca, Vol 9, Iss 4, Pp 418-422 (2004)

Ion-exchange properties of cations from lattice and ions from solutions are characteristic for zeolites. Zeolites as sorbents are used in many branches of industry. Ion-exchange reactions of cations on zeolites have been a theme of many works. With t
