Aluminium Nitrate As External Absorbent In The Microdetermination Of Carbon And Hydrogen In Organofluorine Compounds
MetadataShow full item record
Silica gel loaded with saturated A1(NO3)3- 10. H2O solution proved to be an efficient absorbent for the elimination of the interference of fluorine in the microdetermination of carbon and hydrogen in organofluorine compounds. The reagent is cheap, readily available and easily prepared. Three grams are sufficient for 25 determinations. Samples are burnt in a flow of oxygen using the rapid straight empty tube method. The combustion products are passed through anhydrone, silica gel-aluminium nitrate, and soda asbestos absorption tubes. Carbon and hydrogen contents are determined gravimetrically. The simultaneous microdetermination of carbon, hydrogen and metal, carbon, hydrogen, chlorine or sulphur and metal are carried out successfully in fluorine containing organic compounds.
