In the contemporary world, the major threat posed to sustainable living is pollution. This research work aims to combat ways to remediate water pollution using Calcium Oxide- activated carbon nanocomposite. The nanocomposite used in this study was derived from Chicken eggshell waste as it is a rich source of Calcium. Calcium oxide nanoparticles were synthesized for enhanced performance due to its higher surface area to its volume ratio; it imparts size-dependent properties like higher adsorption tendency. CaO nanoparticles have proven to eradicate harmful metals in polluted water but on the other hand, CaO along with activated carbon is found to be more effective in treating bio pollutants in contaminated water. Hence, in the present study, Calcium oxide was combined with commercially procured activated carbon, and this nanocomposite was used as a potent adsorbent in the bioremediation of Tetracycline hydroxide in polluted water. The nanoparticles were characterized by XRD, FTIR, DLS, HR-SEM AND EDAX. Then the water sample synthesized with the bio pollutant Tetracycline hydroxide was tested for bioremediation efficiency using Calcium oxide - Activated carbon nanocomposite. The degradation of Tetracycline Hydroxide (TCH) was calibrated using a UV spectrophotometer and the degradation percentage was calculated. The UV spectrophotometer results validated that there is 83.12% degradation in the harmful pollutan from the water sample for a period of 5 hours of treatment. This research is an eyeopener as no other experimental work has been done on bioremediation of harmful bio pollutant Tetracycline hydroxide using Calcium oxide-Activated carbon nanocomposite synthesized from chicken egg shell waste using green synthesis.
