Determination of the Chemical Oxygen Demand (COD) of River Water Samples

Introduction The chemical oxygen demand (COD) is a measure of the amount of oxygen consumed by the organic material within a water sample that is oxidized by a strong chemical oxidant, such as potassium dichromate (K2Cr2O7). Its main use is as an indicator of the organic and inorganic matter within water and effluent discharge giving a quantitative value of water quality. There are other tests that are also used to measure the organic …showed first 75 words of 2830 total…
