Evaluation of Biochemical Oxygen Demand for Wastewater Based on 中野, 来紗 1540 黒木, 悠太 1541 下條, 光浩 1542 川上, 満泰 1543 464 BOD mediated biosensor microbial biosensor mediator application/pdf 論文(Article) A mediated biochemical oxygen demand (BOD)sensor system of flow injection mode was constructed by employing carrier solution containing potassium hexacyanoferrate (III) as a redox mediator. An electrochemical flow cell of three electrodes configuration was developed, in which a gelatin layer containing wastewater-assimilating microbes was deposited on the working electrode. The output current was confirmed to yield a peak with a sample injection, and to result from reoxidation of reduced mediator at the electrode. By employing the peak area as the sensor　response,the initial assimilation rate was estimated from the dependence of sensor response on the flow rate of carrier solution. It was demonstrated that reasonable BOD could be obtained for the distillate of a Japanese liquor shochu used as a high BOD wastewater sample. departmental bulletin paper 福岡工業大学 2016-10 VoR application/pdf 福岡工業大学研究論集 1 49 1 7 02876620 AN10036974 https://fit.repo.nii.ac.jp/record/342/files/11478-545_p1.pdf http://hdl.handle.net/11478/545 https://fit.repo.nii.ac.jp/records/342 eng
