Thesis Name： Determination methods for total carbon concentration in water samples Usage： chemistry Keyword： Total carbon concentration; Total organic carbon; Total inorganic carbon Remarks： In this paper, determination methods of total carbon concentration (TC), including total inorganic carbon (TIC) and total organic carbon (TOC) were summarized. TIC determination in natural water samples is essentially vital, especially in sea water samples, for studying the present and future global CO2 air-sea flux. Flow injection analysis (FIA) coupled with a gas diffusion unit (GDU) is proved to be simple, sensitive, rapid and easy to operate for TIC determination. TOC determination is one of the most important works for acquiring knowledge about water and wastewater quality. TOC analysis procedures include two steps, firstly converting the component of organic matter to CO2 and then detecting of the CO2 or carbonate ion in CO2 absorbing solution. Original file： Download
