Could microwave induced catalytic oxidation (MICO) process over CoFe2O4 effectively eliminate brilliant green in aqueous solution?

- The elimination of BG over CoFe2O4(CP) was mainly due to the residue of NaOH.
- Salicylic acid failed to capture hydroxyl radicals within MICO process.
- This study indicated dim prospects for the MICO-based elimination of contaminants.
