XKCF-Ⅱ Fluoride Analyzer Elemental Analyzer Product Name: Fluoride analyzer Product Type: XKCF-II Product Overview: Of coal fluorine is generally between 0.005% -0.03%, a small mining fluorine-containing up to 0.08%, the individual mines can be up to 0.3%. Fluoride is not the lack of the human body, but not excessive intake of elements, but also elements of control of environmental requirements. Coal combustion process, and then through the rain and other environmental factors into the water, directly or indirectly affect human health. Determination of fluoride in coal have a mixed solvent semi-molten coal - Determination of fluoride ion selective electrode potential and high temperature combustion hydrolysis - measuring potential fluoride ion selective electrode methods. The former requires a lot of chemicals and coal samples were semi-molten at a temperature 820 ℃, in addition to a reference to a large number of reagent blanks, but also due to the semi-molten temperature is difficult to control and the introduction of large measurement error. If the temperature is high, there are portions aluminate solution into the sample; low temperature, some of the fluorine-containing mineral is not destroyed, which can cause low measured values. High temperature combustion of the sample solution ion composition obtained by simple hydrolysis method, measuring the potential accuracy, and analysis cycle is shorter than the half-melting method. Therefore, my standard "GB / T4633-2014" using only high temperature hydrolysis method. XKCF-Ⅱ Fluoride analyzer for measuring the determination of fluorine in coal, according to "GB / T4633-2014" high temperature combustion hydrolysis - Determination of fluoride ion selective electrode method total amount of fluoride in coal, for coal, electricity, metallurgy geological prospecting and other departments and laboratory use.
