Silver ions were incorporated into zirconium titanium phosphate (ZTP), a composite ion-exchanger, by an ion-exchange process conducted at 65 °C. This study focuses on the most thorough investigation of their synthesis, optical spectroscopy, absorption band (vibrational and rotational levels) spectra, morphology studies, elemental analysis, and antibacterial activity. Silver-exchanged zirconium titanium phosphates (Ag–ZTPs) were characterized by XRD (BAXS), DRUV–vis, FTIR, XPS, SEM-EDS, TEM, and AAS measurement. Silver ions are incorporated into ZTP which is well-known from X-ray photoelectron study, transmission electron microscopy, and energy dispersive spectra. It was found that 250 mg L–1 of 5 wt % Ag–ZTP possesses high antibacterial activity with 99% inhibition within 12 h of contact. Therefore, the present results strongly suggest the effective use of silver-exchanged zirconium titanium phosphates as antibacterial agents.
