This study presents the synthesis and characterization of a highly selective adsorbent, Nickel(II) Imprinted Polymer (Ni(II)-IPs), for the monitoring and removal of Ni(II) ions. Ni(II)-IPs were synthesized using precipitation polymerization by imprinting the Ni(II)-8-hydroxyquinoline complex into a polymer matrix through the polymerization of methacrylic acid and ethylene glycol dimethacrylate. Successful imprinting and subsequent leaching of Ni(II) ions using HNO 3 were confirmed by FTIR, SEM, and EDX characterization. Adsorption studies revealed that Ni(II)-IPs exhibit a high adsorption capacity of 70.26 mg/g at pH 7 within a short contact time of 15 minutes. Moreover, Ni(II)-IPs demonstrated excellent selectivity towards Ni(II) ions in the presence of competing ions, with relative selectivity coefficients of 1.20, 1.24, and 1.31 for Ni(II)/Cu(II), Ni(II)/Co(II), and Ni(II)/Pb(II), respectively. These findings highlight the potential of Ni(II)-IPs as an efficient and selective adsorbent for monitoring and removing Ni(II) ions from complex aqueous matrices, thereby addressing growing concerns about nickel pollution in Indonesia and beyond.}, issn = {2597-9914}, pages = {307--315} doi = {10.14710/jksa.28.6.307-315}, url = {https://ejournal.undip.ac.id/index.php/ksa/article/view/71382} }
