Se aplica el proceso de intercambio iónico con una zeolita natural obtenida en Taxco, Guerrero, México, para la remoción de Zn, Cd y Ni de soluciones acuosas. Para este proceso, el mineral se homoionizó con cloruro de sodio y posteriormente se puso en contacto con soluciones 0.01 N de sales de nitratos de Zn, Cd y Ni, durante 8 días.
The process which involves ionic exchange was applied with the use of a Mexican zeolitic mineral (Taxco-Guerrero) to remove Zn, Cd, and Ni from an aqueous solutions. Mineral zeoliticsamples in their sodium form were put in contact with Zn(NO3)2,Cd(NO3)2 and Ni(NO3)2 solutions of 0.01 N for 8 days. After the process of ionic exchange, the metallic elements were determined by Electron Microscopy (EDAX). In previous work, the mineral composition was indentified as a mixuture of clinoptilolite and heulandite of the Mexican zeolitic material. Palabras clave: zeolita, clinoptilolita, metales pesados
