Abstract:

This study aimed to investigate the ability of calcium carbonate mineral (Calcite) and calcareous soils as an adsorbent to remove heavy metals (Cu) in aqueous media by using the mechanism of adsorption phenomena. Isotherm adsorption was conducted using the Batch technique, using different Cu concentrations of (0, 5, 10, 50 and 100) µg Cu.ml- for 24 hours. at 298K. The results showed that copper adsorption on the Calcite mineral surface was 2019 mg.kg-1 while the number of Cu-removals in calcareous soils increased as soil carbonate minerals content increased and ranged between (2035-2487) mg.kg-1. The magnitude of calcium carbonate on Cu adsorption as active masterly in the adsorption. R² (0.87) Kd for soils (230-7556) were than carbonate minerals (258) L.Kg-1 also Langmuir parameters values adsorption for calcareous soils were more than calcium carbonate mineral (Calcite) respectively, (Xm), (1429, 4526) mg kg-1), L (0.125 120.5) L mg-1, MBC, 178.63 2590.3) Kg-1 and RL 0.102 0.779), for mineral (Calcite) and calcareous soils respectively and the adsorption process was spontaneous.
