文章介绍了水中生物耗氧量、化学耗氧量、总有机碳和总耗氧量的测定原理、仪器和进展。

Taking tetramethoxysilane (TMOS) and dimethyldimethoxysilane (DiMe-DMOS) as precursors for the synthesis of an organically-modified silicates (ORMOSILs), optical BOD sensing films immobilizing five kinds of limnetic microorganisms were composed by poly(vinyl alcohol) ormosils matrix.

利用四甲氧基硅烷(TMOS)、二甲基二甲氧基硅烷(DiMeDMOS)与聚乙烯醇(PVA)构成的有机改性材料分别包埋五种不同淡水耗氧菌,制备光化学生物耗氧量(BOD)的传感敏感膜,并在自行构建的BOD测定仪上考察其光谱响应行为。

The biological oxygen consumption mechanism of the sediment in Dagu river estuary is studied through the oxygen consumption simulation experiment in the sediment-water interface.
