Xkcf-a Fluoride Analyzer

Owing to our years of industry experience and market understanding, we are leading Exporter & Manufacturer of XKCF-a Fluoride Analyzer in Hebi, Henan, China.
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 a , 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.
