In this paper,a new method was developed for the treatment of brilliant green wastewater.The method involved the utilization of microwave radiation to the wastewater in the presence of activated carbon and air.The influences of several factors on the removal efficiency were studied in detail.From the experimental results,some important conclusions were obtained and were presented as follows:(a) The pyrolysis and oxidation of brilliant green are catalyzed by microwave radiation.(b) The removal rate of brilliant green was directly proportional to the microwave power,radiation time,amount of activated carbon and initial concentration of brilliant green.(c) The removal rate reached 98.69% under optimum conditions.The results suggested that this proposed method may be useful for the treatment of brilliant green wastewater.
