Lab Junction 12 Tubes COD Digestion Apparatus for Laboratories LJ-070 is a laboratory instrument used for the determination of the chemical oxygen demand in water and wastewater samples. The chemical oxygen demand is a measure of the amount of organic pollutants present in a sample that can be oxidized by a strong chemical oxidant.
The COD digestion apparatus consists of a heating block or a set of digestion tubes specifically designed to withstand high temperatures. The apparatus utilizes a strong oxidizing agent, typically a mixture of potassium dichromate (K2Cr2O7) and sulfuric acid (H2SO4), to oxidize the organic compounds present in the sample.
The process begins by adding the water or wastewater sample into the digestion tubes or vessels. The appropriate amount of the oxidizing agent is then added to the sample. The digestion tubes are sealed to prevent any loss of volatile compounds during the process. The tubes are then placed in the heating block, which is preheated to a specific temperature, typically around 150-165 degrees Celsius.
During the digestion process, the strong oxidizing agent reacts with the organic compounds in the sample, converting them into carbon dioxide (CO2) and water (H2O). This reaction is facilitated by the high temperature and the presence of the sulfuric acid catalyst. The heating block maintains a constant temperature throughout the digestion period, which is typically around 2 hours.
After digestion, the tubes are removed from the heating block and allowed to cool. The resulting solution is then ready for further analysis. The COD level in the sample is determined by titration or colorimetric methods, where a reagent is added to the digested sample to measure the amount of residual oxidizing agent or the color intensity formed due to the reaction.
