Resumen:
A removal method for arsenic in polluted water using
zeolites was evaluated. Natural and commercial zeolites were used; the second
one was also treated with iron (T-CZ). Adsorption isotherms were evaluated. Pure
natural zeolites had more adsorption capacity than commercial ones, and that
T-CZ improved the adsorption significantly. Also, experiments at pH 5.5 showed
better adsorption capacities compared to those at lower pH values. T-CZ
represents a novel material that may be used as filter for Arsenic-contaminated
waters.
