This research is part of the study of the adsorption capacity of ions of Al +3 +2 , Cu and +2 Pb , with natural zeolites, by identifying the parameters and conditions required in the adsorption process. The aim of the research was to determine the removal efficiency of Al+3, +2 Cu +2 and Pb ions in a natural zeolite filter. An experimental plan was established consisting of the phases of physicochemical characterization of zeolite, analysis of the effect of pH on the adsorption process, assessment of its adsorption capacity, determination of adsorption kinetics, and design and construction of the natural zeolite filter. The results of the research were: Natural zeolites according to X-ray diffraction (XRD) analysis results are composed of montmorillonite, cristobalite, clinoptilolite, plagioclase and quartz; they have a surface area 2 of 26.87 m /g; a pore volume of 0.36 ml/g and apparent and real density 0.70 g/ml and 1.82 g/ml respectively. Natural zeolites have a greater capacity to remove Pb +2 +2 and Cu ions at pH = 4, and at pH = 3.5 for Al +3 . They were determined to have an adsorption capacity of +3 1.54 mg Al /g zeolite, 3.19 mg Cu +2 /g zeolite and 7.30 mg Pb +2 /g zeolite and to have a better fit with the Langmuir isotherm model with R 2 values of 97.6 for Pb +2 , 99.58 for Cu +2 , 98.39 +3 for Al . The kinetics of the adsorption process of natural zeolites conformed to the pseudo- second order model with a kinetic constant of 0.090 g/mg*min. The design of the zeolite filter was based on the data obtained from the experimental fit. It is concluded that it was possible to remove Al +3 +2 , Cu +2 and Pb ions from the aqueous solutions through the adsorption process by applying a natural zeolite filter designed with efficiencies greater than 98%.
