| Abstract: | The measurement principle, analytical flow path and characteristics of HBCOD - 1 online automatic COD monitor are introduced in the article. By using organic and reducing inorganic substances in wastewater oxidized by K2Cr2O7 in acidic medium and produced Cr3+ , chemical oxygen demand (COD) can be measured by the monitor through Vir spectrometry. The measured COD values are in good consistency with CODCr values obtained through standard method after calibration by linear regression. |
