Synthesis of nano ZnS thin film by chemical bath deposition method and its application for the removal of Victoria blue dye

Nanocrystalline thin films of ZnS are deposited using chemical bath deposition technique. Crystallite size of nanocrystalline film was determined from XRD data and was found to be 2 nm. The energy band gap of the nano thin film was determined from UV spectrograph, it was found to be 3.16 eV. The ZnS nano thin film was employed for the photocatalytic degradation of water soluble Victoria blue (VB) dye. Various parameters like pH, initial dye concentration and contact time have been studied and optimized. The optimum pH was 8 and equilibrium contact time was found to be 30 min for the photocatalytic degradation of the VB dye.
