Chemical oxygen demand (COD) is a crucial metric for assessing the organic pollution load in water, reflecting the amount of oxygen required to oxidise organic compounds. Ultraviolet–visible (UV ...

Technical Terms Chemical Oxygen Demand (COD): A quantitative measure of the amount of oxygen required to chemically oxidise organic compounds in water.

The Thermo Scientific Orion 3106 chemical oxygen demand (COD) analyzer provides wastewater treatment plant engineers with another tool to monitor wate ...

Current chemical oxygen demand (COD) analyses generate wastes containing hexavalent and trivalent chromium, mercury, and silver. Waste disposal is difficult, expensive, and poses environmental hazards ...

However, while microbial electrochemical sensors (MESs) employing electroactive biofilms (EABs) as sensing elements can measure BOD in municipal wastewater, their performance in saline ...

The oxygen consumption was then correspondingly high. Experts refer to the "biological oxygen demand" (BOD) in this measurement.

Ethylenediaminetetraacetic acid (EDTA) was found to incompletely oxidize in chemical oxygen demand (COD) analysis, leading to incorrect COD values for water samples containing relatively large amounts ...
