AB  - A study was carried out to investigate the degradation of organic contaminants 
      (Congo red and Reactive yellow - 105) using cellulose acetate - polystyrene 
      (CA-PS) membrane with and without ZnO impregnation. Scanning electron microscope 
      (SEM), electron dispersive analysis of X-rays (EDAX), Fourier transform infrared 
      spectrometer (FTIR), atomic force microscope (AFM) and thermogravimeric analysis 
      (TG-DTA) analysis were carried out to characterize bare and ZnO impregnated CA-PS 
      membranes. Membrane efficiency was also tested for pure water flux and 
      antifouling performance. The modified membrane showed almost 85% water flux 
      recovery. Blending of ZnO nanoparticles to CA-PS matrix could decrease membrane 
      fouling and increase permeation quality of the membrane with above 90% of 
      photocatalytic degradation efficiency for dyes. The rate of degradation of dyes 
      was observed using UV-Vis spectrometer. Reusability of CA-PS-ZnO membrane was 
      studied and no significant change was noted in the degradation efficiency until 
      fourth cycle. Langmuir-Hinshelwood kinetic model well describes the photo 
      degradation capacity and the degradation of dyes CR and RY - 105 exhibited 
      pseudo-first order kinetics. The regression coefficient (R) of CR and RY - 105 
      found to be 0.99. The novelty of the prepared CA-PS-ZnO membrane is that it has 
      better efficiency and high thermal stability than our previously reported 
      material. Therefore, ZnO impregnated CA-PS membrane had proved to be an 
      innovative alternative for the degradation of CR and RY - 105 dyes.
