Organic dyes used in the food and textile industries are primary sources of environmental contamination due to their high toxicity nonbiodegradability. This paper describes synthesis cellulose nanocrystals/zinc oxide (CNC/ZnO) nanocomposite via sol-gel method. Various characterization techniques such as FTIR spectroscopy, UV-Vis FESEM-EDX analysis were done. analyses initially confirmed formati...
