摘要
介绍了Elox 100A COD 在线自动监测仪的测量原理、分析流程和主要特点。仪器采用羟基自由基(OH)氧化水中有机物,通过计算电流变儿测得水中化学需氧量(COD值)。与国标方法进行线性回归校正后,仪器测量值与国标方法测得的COD_(cr)值具有较好的一致性。
The measurement principles, analytical flow path and characteristics of Elox 100A online automatic COD monitor are described.The organic substances in water are oxidized by OH-radicals, at the same time the change of current takes place on the working elec-trode . The values of COD are obtained by calculating the change of current. The measured COD values are in good agreement withCOD cr values obtained by standard method after calibration by linear regression .
