Influences and Isotherm Models on Phosphorus Removal from Wastewater by Using Fe3+-Type UBK10 Cation Exchange Resin as Absorbent

Abstract

Phosphorus is a nutrient that is required for life. Eutrophication, on the other hand, is caused by an overabundance of phosphorus in the hydrosphere. Eutrophication is a form of water pollution that can be solved by removing phosphorus from the environment. Adsorption with cation exchange resin is a more practical method for removing phosphate ions at low concentrations than traditional approaches. The column approach is good for recovering phosphate effectively. As a result, a superior adsorption ability of the column and a practical regeneration process are critical. Accordingly, the goal of this study is to design a phosphate ion recovery system using a Fe-type cation exchange resin (Fe3+-type UBK 10) column. The batch approach was used to investigate the characteristics influencing the adsorption of phosphate ions on Fe-type UBK 10 in order to better comprehend the mechanism of adsorption. The number of phosphate ions adsorbed increased with increasing reaction time, according to the findings. The best results were achieved using 3 g of resin in 0.05 M NaCl at pH 6. The best fit was found in the Langmuir isotherm using equilibrium data.
