Abstract:The BOD biosensor used a double-layered mem-brane has lots of problem, as low response, narrow measuring range, and poor stability. For solving these problems, the method of BOD biosensor by suspending gel beads has been developed, which has high re-sponse, wide measuring range and fine stability. By using the sensor, a linear range was obtained up to 500mg/L BOD, its linear coefficient correlation was more than 0.99, and the response time was 12min. The sensor has a good repeatability. The output of the sensor was constant for over 4 months, and it has well interrelated to which determined by using conven-tional BOD5 analysis method.
Keywords:BOD Microbial sensor Detection
