北京純水TOC分析儀介紹  水樣中TOC的分析步驟

水中的有機(jī)物質(zhì)的含量，以有機(jī)物中的主要元素一碳的量來表示，稱為總有機(jī)碳。TOC的測定類似于TOD的測定。在950℃的高溫下，使水樣中的有機(jī)物氣化燃燒，生成CO2，通過紅外線分析儀，測定其生成的CO2之量，即可知總有機(jī)碳量。

北京純水TOC分析儀介紹  水中TOC的監(jiān)測

我們的生活離不開水，若相當(dāng)多的有機(jī)污染物存在于水中，將直接影響水體的質(zhì)量，對我們的生活和生產(chǎn)造成危害，因此水和廢水的監(jiān)測，越來越引起人們的重視。其中水體中總有機(jī)碳(TOC)含量的檢測，日益引起關(guān)注。它是以碳含量表示水體中有機(jī)物質(zhì)總量的綜合指標(biāo)。TOC的測定一般采用燃燒法，此法能將水樣中有機(jī)物全部氧化，可以很直接地用來表示有機(jī)物的總量。因而它被作為評價(jià)水體中有機(jī)物污染程度的一項(xiàng)重要參考指標(biāo)。

Analysis steps of TOC in water samples

The content of organic matter in water, expressed by the amount of carbon, the main element in organic matter, is called total organic carbon. The determination of TOC is similar to the determination of TOD. At a high temperature of 950℃, the organic matter in the water sample is gasified and burned to generate CO2. The total organic carbon content can be determined by measuring the amount of CO2 generated through an infrared analyzer.

Monitoring of TOC in water

Our lives cannot do without water. If a considerable amount of organic pollutants exist in water, it will directly affect the quality of the water and cause harm to our lives and production. Therefore, the monitoring of water and wastewater is increasingly attracting people's attention. The detection of total organic carbon (TOC) content in water bodies is increasingly attracting attention. It is a comprehensive indicator that represents the total amount of organic matter in water using carbon content. The determination of TOC generally adopts the combustion method, which can oxidize all organic matter in the water sample and can be directly used to represent the total amount of organic matter. Therefore, it is regarded as an important reference indicator for evaluating the degree of organic matter pollution in water bodies.
