Adsorption Kinetic of Mn(II) Ions in Synthetic Acid Mine Water Using Calcium Carbide Residue as an Adsorbents

This investigation concentrated on diminishing the centralization of Mn(II) particles in manufactured corrosive mine water by the adsorption strategy utilizing calcium carbide buildups as an adsorbent. The adsorption procedure was examined utilizing 100 mL of arrangement of engineered corrosive mine with differing pH of 2.5 to 5 and weight of calcium carbide buildup from 2.5 to 7.5 g. The blend was mixed utilizing a shaker with speed of 200 rpm for 180 minutes with contact time ranges (5, 10, 20, 30, 40, 50, 60, 90, 120, 150, and 180 minutes) and the underlying centralizations of Mn(II) of between 20 to 100 mg/L. The outcomes demonstrated that adsorption limit of adsorbent increments with expanding of starting grouping of Mn(II) particles in the arrangement. The Freundlich isotherm model matches the observational information. Adsorption energy demonstrated that this response pursues the pseudo-second adsorption model. The most extreme adsorption limit with respect to Mn(II) as arrangement is 41.67 mg/g at pH 5. The outcomes additionally shown that calcium carbide buildups are reasonable for adsorbing Mn(II) particles from fluid arrangements.
