This research aims to synthesize the NiFe2O4/Chitosan-PVA/SnO2 composite as an effort to address tetracycline waste pollution in the environment. Nanomagnetic NiFe2O4 is utilized to reduce the band gap of SnO2 and also to impart magnetic properties. Chitosan-PVA is employed as a coating, while SnO2 serves as the photocatalyst. The NiFe2O4/Chitosan-PVA/SnO2 composite is synthesized using the cop…
