ABSTRACT
Man’s day-by-day activities have a big impact on the environment so we continuously search fordifferent methods of cleaning it. In this paper is studied a very efficient way to purify the residual waters usingnatural ions exchangers. There are made a series of studies above the zeolites, as a class of specific structuresilicates. The main characteristic of the zeolites is the presence of some loose water molecules, the concedingand readmission of these being done without any damage to the crystal lattice. The paper contains a kineticstudy regarding the copper’s elimination from the residual waters, using the Mirsid volcanic tuff. Theexperimental study of the ionic exchange reaction permitted the appraisal of the speed limit stage and theinfluence of the parameters over the purifying process of the residual waters.
