By definition, chemical BOD Test oxygen demand is “a measure of the oxygen equivalent Of the three test methods that determine oxygen of the organic matter content of a sample that is suscep- demand (BOD, COD and TOC), the BOD test most tible to oxidation by a strong chemical oxidant.”*.
average 8.35 mg/l. The biochemical oxygen demand (BOD) for 10 sampling stations were recorded between 0.84 mg/l to 1.64 mg/l, with the average value of BOD reading was 1.53 mg/l. Chemical Oxygen
Biochemical oxygen demand, or BOD, is a chemical procedure for determining the amount of dissolved oxygen needed by aerobic biological organisms in a body of water to break down organic material present in a given water sample at certain temperature over a
16/3/2011 · Mar 16 2011. CHEMetrics (USA) offer an economical line of reagent vials for performing chemical oxygen demand (COD) measurements. Chemical Oxygen Demand (COD) measurements are frequently performed in municipal and industrial laboratories to measure the overall level of organic contamination in wastewater.

Tygon and black rubber can add oxygen demand to the water. When volumes of sample used exceed 150 ml, additional nutrients should be added to the sample bottle. Add an additional 0.1 mL of nutrients for each 50 mL of sample used in excess of 150 mL.
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 (70–700 mg/L)
13/7/2009 · Chemical oxygen demand (COD) is a measure of the capacity of water to consume oxygen during the decomposition of organic matter and the oxidation of inorganic chemicals such as ammonia and nitrite. COD measurements are commonly made on samples of waste watersor of natural waters contaminated by domestic or industrial wastes.
