Abstract
For the analysis of fluorine in difficult-to-burn and complex organofluorine compounds, special additives have been developed to ensure complete decomposition of the substances. Using a spectrophotometric technique based on the formation of а fluoride complex with lanthanum alizarin complexone, various organofluorine compounds have been analyzed with fluorine content of 1.5 to 70 % containing heteroelements in their structures: sulphur, chlorine, bromine, phosphorus, boron, selenium, tellurium in various combinations, as well as metals. The error of determination was established to be not higher than 0.5 abs. %
