WebDissolved organic carbon is the predominant material that absorbs UV, and rapid attenuation occurs with moderate dissolved organic carbon concentrations (i.e., more than several mg C liter−1). From: Freshwater Ecology (Second Edition), 2010 View all Topics Add to Mendeley About this page Dissolved organic carbon Total organic carbon (TOC) is an analytical parameter representing the concentration of organic carbon in a sample. TOC determinations are made in a variety of application areas. For example, TOC may be used as a non-specific indicator of water quality, or TOC of source rock may be used as one factor in … Meer weergeven Since all TOC analyzers only actually measure total carbon, TOC analysis always requires some accounting for the inorganic carbon that is always present. One analysis technique involves a two-stage … Meer weergeven Virtually all TOC analysers measure the CO2 formed when organic carbon is oxidized and/or when inorganic carbon is acidified.
