摘要：
The use of ALG beads and ALG-ZEO beads for the removal of Cd2+ was evaluated in a batch system, was determined the effect of pH, kinetics and adsorption isotherm. The characterization was carried out by FTIR, SEM and EDS. The EDS analysis showed that the main elements are C, O and Ca, these are associated with the chemical composition of alginate while the ALG-ZEO bead showed characteristic crystals of the zeolite. Cd2+ adsorption was carried out at pH 6 using ALG beads and ALG-ZEO beads as adsorbent. The suggested mechanism to explain the removal of the Cd2+ ion was is through a chemisorption process. Finally the adsorption process was adjusted to kinetic and isotherm models.
