![]() SC-XRD and Raman reveal that melamine acts as tridentate ligand towards three different Ag (I) through the threetriazine-nitrogen atoms. MO− was almost completely removed (95 mg g−1 under the specified initial concentration) with no significant removal of MB+, which encourages its use as a material for the selective removal of the anionic contaminants from wastewater.Ī new cationic Ag(I)-melamine coordination polymer (AgM-CP), n, was syn-thesized in acidic aqueous solution and characterized via FTIR, Raman, SEM/EDX, SC-XRD, PXRD, and BET. ![]() Due to these properties, AgM-CP was examined for the selective removal of anionic methyl orange (MO−) competitively with the cationic methylene blue (MB+) using aqueous solution of these synthetic dyes. AgM-CP structure is suggested to be cationic, and highly water-stable as concluded from weight loss calculations, PXRD, and Raman analyses. SEM shows that AgM-CP has a bar-like macro-structure with considerably large dimensions, e.g. Raman and FTIR, together, confirm the formation of coordination bonds between the electron-donor nitrogen atoms and the electron-acceptor silver(I). Raman results confirm the crystalline nature of AgM-CP as given by SC-XRD.
