| 中文摘要 |
| 本文介绍了用四种微生物膜制备的BOD电极及其测定废水BOD的试验情况,结果表明,电极对BOD际准物质线性响应范围为10-60mg/L,响应达到平衡时间为4 min(对低限浓度溶液)到7 min(对高限浓度溶液),连续稳定地工怍寿命在20天以上;用该电极和BOD5标准法对照测定7种废水的BOD值,测定结果的相关性较好。 |
| 英文摘要 |
| The electrodes of four different microbial membranes have been prepared for determining BOD in waste-water. The linear response range of the electrodes is 10-60 mg/L for BOD certified reference materials. The time for reaching equilibrium is between 4 minutes (for io\v limit concentration) to 7 minutes(for high limit concentration). The electrodes has sustained the initial sensitivity over 20 days. Compared with the standard method for five days, the microbial electrodes prepared for de-termination of BOD have obtained good results. |
