Definitions for "Total organic carbon"
The concentration of organic matter in the sediment, expressed in terms of carbon (MW = 12.00) a dry weight basis (usually g/kg or mg/kg).
represents the total organic carbon in a given sample. Determined by oxidation of the organic matter with heat and oxygen or chemical oxidants, followed by the measurement of the H2O liberated with an infared analyser.
The organic carbon in wastewater is composed of a variety of organic compounds in various oxidation states. The TOC is a more convenient and direct expression of total organic content than either the BOD or COD, but does not provide the same information. TOC measurement does not replace BOD and COD testing.
