Como realizar análise da DQO - Demanda Química de Oxigênio [Método Espectrofotômetro]

Chemical Oxygen Demand (COD) is defined as a measurement of the oxygen consumption capacity through chemical oxidation of organic matter present in a sample. Therefore, COD [Spectrophotometer Method] is one of the most widely used parameters for indicating water and wastewater quality. COD results are also widely used to calculate removal and measure the efficiency of wastewater treatment plants.
