Permanganate index vs cod
The permanganate index is an assessment of water quality. It involves the detection of oxidation by potassium permanganate in an acid medium under hot conditions. The method is to heat a sample in a boiling water-bath with a known amount of potassium permanganate and sulphuric acid for a fixed period time (10 min). Part of the permanganate will be reduced by oxidizable material in the sample. The consumed permanganate can be determined … WebThe ratio of chemical oxygen demand and permanganate index is 2.71:1, and their linear regression equation is y = 3.337x - 0.7519.

WebOct 14, 2010 · Some wastewater parameters (e.g., heavy metals) are often reported in smaller units such as micrograms per liter (µm/L) or parts per billion (ppb). COD (chemical oxygen demand) COD is the most popular alternative test to BOD for establishing the concentration of organic matter in wastewater samples. Websystems.2 COD measurement involves determining the number of oxygen equivalents consumed in the oxidation and decomposition of organic compounds in a sample with powerful oxidizing reagents, such as dichromate or permanganate under defined conditions. In China, the permanganate-based method is designated as permanganate index (COD …
WebA new spectrophotometric method for measuring permanganate index (chemical oxygen demand using potassium permanganate (KMnO 4) as oxidant, COD Mn) in water was established.The method was based on the rapid oxidation of N,N-diethyl-p-phenylenediamine (DPD) by residual KMnO 4 in digestion solution under neutral pH condition to form the … WebTests such as the COD (Chemical Oxygen Demand), BOD (Biochemical Oxygen Demand) and Permanganate Index are a measure of the oxidisable content of water and a guide to the …
WebThis International Standard specifies a method for the determination of the permanganate index of water. It is primarily intended for water for human consumption and domestic use, drinking water, natural mineral water, well and table water, as well as water from swimming pools. It is used for the determination of the parameter "oxidizability". WebThe basic principles of the two methods are similar, but since potassium permanganate is less oxidizing than potassium dichromate, the concentration after analysis is lower than …
