The chemical oxygen demand (COD) is a measure of water and wastewater quality. The COD test is often used to monitor water treatment plant efficiency. This test is based on the fact that a strong oxidizing agent, under acidic conditions, can fully oxidize almost any organic compound to carbon dioxide. The COD is the amount of oxygen consumed to chemically oxidize organic water contaminants to inorganic end products.

3. Use the test procedure to measure the BOD concentration of the sample. After sample dilution, select a BOD range and sample volume. 4. Multiply the test result by 5 to get the concentration of the sample before dilution. Prepare the dilution water Make sure that no source of oxygen demand or toxins are added when the dilution water is prepared.
Nov 19, 2020 · The COD Test Tube produced by Aijiren is often used for chemical oxygen demand testing. The process is as follows: 2mL of water or fresh water sample is added to a 16mm glass culture tube containing digestion agent and catalyst. Cover the tube with a polypropylene lined polypropylene tube and heat it in a block digester at 150°C for 2 hours.
This polypropylene (PP) conical centrifuge tube comes with a high density polyethylene (HDPE) blue cap. This tube is a premium, high quality tube developed for functionality, flexibility, and ease of use in the lab. Contamination risk is reduced as tubes are sterile with a 10-? SAL.
The Chemical Oxygen Demand (COD) test is widely used as a measure of organic contamination by determining the quantity of oxygen required for oxidation of reduced species including organic matter, in a water sample using a specific oxidizing agent, temperature and time reduction.

mL of sample to the test vial. 3. Immediately put the cap on the vial. Hold the vial by the cap, over a sink. Shake the vial quickly. The vial gets very hot during mixing. 4. Clean the vial. 2 Oxygen Demand, Chemical, Reactor Digestion TNTplus Method (7–70 mg/L)
Chemical Oxygen Demand (COD) is one of the most widely used parameter for water quality monitoring and assessment. It provides information about the readily oxidized fraction of the organic load or reduced compounds in waters, indicating the degree of water pollution [1]. COD therefore plays an important role in water pollution control and
Chemetrics K-7355 Chemical Oxygen Demand (COD) Test Vial Kits, 0-150ppm Low Range. COD Vials Kit. Catalog No.: K-7355. Range: 0-150 ppm (LR) USEPA-accepted*. Method: Dichromate Reactor Digestion. 150 vials. Hach Equivalent Cat. No.: 21258-15.
rivers), making COD a useful measure of water quality. It is expressed in milligrams per liter (mg/L), which indicates the mass of oxygen consumed per liter of solution. COD is the measurement of the amount of oxygen in water consumed for chemical oxidation of pollutants. COD determines the quantity of oxygen required to oxidize the organic
COD (Chemical Oxygen Demand) is a term used to measure the quality of water ; It is a measure of water pollution resulting from organic; Among the various methods and instruments available, a non-dispersive absorption based instrument has been found to be the best for this
of heavy metal pollution. Atasie and Egbonu (2017) examined some water quality indicators and the impact of water samples from Aba Waterside River, Aba on the hematological indices of rats. In their study, water quality analysis was limited to biochemical oxygen demand, chemical oxygen demand, dissolved oxygen and total hardness.
