One approach to address this issue is photocatalytic antibiotic degradation in water systems using chalcogens in the form of thin films. In the current study, chemical bath deposition (CBD) technique was used to deposit the SnS<sub>2</sub> and Zr<sub>1-x</sub>Sn<sub>x</sub>S<sub>2</sub> (x = 0.6) thin films. Using XRD, the structural characteristics of the thin films that were deposited were investigated. Analysis of the absorption spectra showed that the thin films possessed optical bandgaps of 3.7 and 4.3 for SnS<sub>2</sub> and Zr<sub>1-x</sub>Sn<sub>x</sub>S<sub>2</sub> (x = 0.6), correspondingly. A range of parameters were examined, including starting CIP concentrations of 1, 3, 5, and 7 ppm, pH levels of 5, 7, and 11, and irradiation periods (30, 60, 90, and 120 min). The pseudo-second order and Langmuir models were employed to assess the kinetic process.
