Abstract: The TiO2-ZnO, TiO2-ZnO-ED and TiO2-ZnO-ED-HPV (TZEDHPV) nanocomposite were successfully prepared by simple hydrothermal process The nanocomposite was characterized and conformed by DRS-UV, FT-IR, XRD, SED and EDX analsis. The DRS-UV analysis of TZEDHPV nanocomposite absorption was increased with the band gap decrease of TiO2-ZnO by the addition of heteropoly acid (HPV). The FT-IR spectra of photocatalyst, presents the characteristic bands of metal oxide, ED and HPV. SEM and EDX analysis reveals clustered microsponge-like structure of catalyst with more number of cavities. Photodegradation of ciprofloxacin (CF conc.: 40 µM), exhibited 98.20 % removal efficiency under UV light. According to the scavenger method results, O2•- radical played a main role in the photocatalytic degradation.
