The most important natural resource for human health and well-being is water, which can be affected by different sources, such as physical, organic, chemical, and microbiological ones. CBV 760 commercial zeolite was used and tested to remove inorganic pollutants, lead, and cadmium. Adsorption isotherms were used to assess the adsorption properties of contaminants and real effluent. At the solution pH (4.5 and 5), adsorption kinetics and isotherms were conducted for lead and cadmium, respectively. The investigated zeolite was quite efficient in lead and cadmium removal, as the maximal adsorbed amounts were Qa = 175 and 148 mg g−1 for lead and cadmium, respectively, at T = 308 K. Adsorption capacity is pH dependent. Adsorption of Pb2+ and Cd2+ is highest at pH 8 (Qa = 107 and 53.58 mg g−1, respectively). The CBV 760 displays more affinity for Pb2+ than Cd2+. It is worth noticing that CBV 760 exhibits good selectivity for heavy metal retention metals, namely, Ni2+, Cu2+, Cd2+, and Pb2+, in an actual contaminated effluent with a removal yield of 80% on CBV 760.
