In the vast aqueous expanse that sustains life, an invisible intruder silently corrodes the purity of our precious resource. Once celebrated for their role in essential biochemical processes, Ferric ions have now emerged as an alarming source of water pollution. With their ability to infiltrate aquatic ecosystems undetected, these iron warriors wreak havoc on the delicate balance of nature. This work embarks on the preparation of a Fe(III)-Imprinted Selective Polymer(Fe(III)-ISP)for removing ferric ions from various water samples. The polymer network was synthesized from Ferric Nitrate, Alginic acid, and Acrylamide using potassium persulphate as initiator and crosslinking agent N, N′-Methylenebisacrylamide. The polymer network was characterized by Fourier Transform IR, UV-Visible spectroscopy, Scanning Electron Microscopy, and SEM-EDS spectrum. The effect of different parameters like PH, Concentration, amount of polymer added, and time on ferric ion uptake was investigated. The method was applied for the adsorptive removal of ferric ions from different real water samples collected from the environment.
