Total Organic Carbon (TOC) is defined as the amount of carbon bound in an organic compound and is often used as a non-specific indicator of water quality or cleanliness of pharmaceutical manufacturing equipment.
Carbon Cycle ? Carbon is an essential building element for all organic compounds. The cyclic flow of carbon in Nature is known as the carbon cycle. o In Nature, the most abundant source of carbon exists as carbon dioxide free in the atmosphere and dissolve in oceans. o During photosynthesis...
Total Organic Carbon(TOC) is one of the most important composite parameters in theassessment of the organic pollution of water. Since it includes all carbon compounds as one mass, it is exactly defined and an absolute quantity. Therefore, it may be determined directly. In relation to the TOC...
