Removal of benzotriazoles from domestic wastewater using Pleurotus ostreatus fungal pellets
The Canadian Journal of Chemical Engineering, EarlyView.Removal of benzotriazoles from domestic wastewater using a fungal pellet reactor with Pleurotus ostreatus. The system effectively removed CBTR (70%), while BTR (19%), 5‐TTR (17%), and OH‐BTH (16%) showed moderate removal. Abstract Benzotriazoles are a group of persistent and mobile substances commonly found in aquatic environments due to inefficient ...
