Textile dyeing industry effluents require advanced treatment technologies such as adsorption for the removal of dyestuffs. In this Study Chitosan Zinc Oxide Nano composite was used as an adsorbent for removal of sample that contains two reactive dyes: Reactive Black HN and Reactive Magenta HB from textile dying industry effluent. The color removal performance of Chitosan Zinc oxide Nanocomposite has been investigated using parameters such as temperature, composite loading, time of contact and turbidity. It was found that composite exhibits dye removal efficiency that is about 95-99%. Batch adsorption studies of color removal from effluents of Textile dyeing industry were carried out using Chitosan-zinc oxide Nano particles composite. Results showed that color adsorption increases with the increase of the dosage of composite. In this study, optimum dosage was found for the removal of dye from Textile effluents. It was found that using 2 gm of Composite per liter of effluent at ambient temperature (50°C) and 60 minutes time of contact, it may be possible to remove 99% of the original color of the effluent.
