Removal of Sulfate Pollutants from Water Using Zinc/Aluminum Layers
摘要
The nanostructures were prepared with a ratio of 3:1 of zinc chloride and aluminum chloride by co-precipitation method. These layers were used to adsorb sulfate ions (SO4−2) from the contaminated water. These layers were identified with FTIR, XRD and AFM. The results showed that the increase in temperature increases the amount of adsorption, where at the temperature of 45 °C it gave the highest amount of adsorption. As for the results that led to an increase in acidity, the amount of adsorption increased, as (pH = 2, 4, 7, 9, 12) and the highest amount of adsorption was at pH = 2. S2 type adsorption isotherms were defined for glaze classification. The percentage of removing sulfate ions from the water was calculated for the geographical change, and the most prominent results are that the highest percentage in time is 250 min. The thermodynamic functions (∆H, ∆G, ∆S) were calculated for the performance of sulfur ions and the results. Keywords—component, formatting, style, styling, insert showed that the reaction is endothermic and non-spontaneous.
