In the present study, biochars from rice husk were synthesized via pyrolysis at 400, 550, 700 and 850 °C for 1 h under a limited O2 atmosphere, characterized with various techniques of used as catalysts to activate persulfate degrade sulfamethoxazole (SMX). After physicochemical characterization biochars. SMX degradation tests performed using different water matrices, biochar concentrations ini...
