介绍一种以微生物膜电极为传感器的BOD快速测定仪的原理、结构、技术性能和应用。仪器传感器的寿命可达一年以上;对BOD物质的线性响应范因2～60mg/L;响应时间4min(低浓度)～8min(高浓度);测定环境标准水样变异系数≤2.0;与BOD_5经典方法同步测定废水样品,结果相关性良好,是一种具有实用价值的分析仪器。
A principle, structure, technical performance and application of a BOD rapid detector with a microbial membrane electrode as a sensor are introduced. The life span of the instrument sensor can reach more than one year; the linear response of BOD substance is 2 ~ 60mg / L; the response time is 4min (low concentration) ~ 8min (high concentration); the coefficient of variation of environmental standard water sample is ≤2.0; The classical method of simultaneous determination of wastewater samples, the results of a good correlation, is a practical analytical instruments.
