Application of Rapid Biochemical Oxygen Demand Biosensor
Abstract:
Multiple-species BODseed was used for fabricating biochemical oxygen demand(BOD) biosensors for rapid online BOD determination.Some factors to accuracy were studied such as calibration solution selection,sample self-biodegradation,and thermostatic device.Good results were obtained when wastewater was used as calibration solution instead of glucose and glutimic acid(GGA).The self-biodegradation process made the rapid measurements inaccurate.Besides,thermostatic device used only for biosensors is defective,and it should be applied for maintaining a constant temperature of the samples and buffer,promoting the efficiency and accuracy of online monitoring.
