摘要
以性能优良的酿酒酵母菌作为敏感材料 ,采用聚乙烯醇包埋方法获得了响应大、测量范围广、稳定性和准确度较好的BOD微生物传感器。该传感器测定BOD ,其线性响应范围为 0～ 2 0 0mg/L ,线性相关系数达到 0 .99以上 ,响应时间在 15min内。测定结果与标准五天法具有良好的相关性 ,连续稳定工作寿命在
A yeast immobilized by PVA, was employed for the sensitive material BOD sensor. The sensor has high response, wide measurement range, good stability and specificity. By using the sensor, a linear range was obtained up to 200mg/L BOD, its linear coefficient correlation is more than 0.99, and the response time is in 15min. The output of the sensor is constant for over 1 month, and it was well interrelated to what determined by using conventional BOD 5 analysis method.
