Sawyer, A E; Spencer, A R

The development of a method for the determination of microgram quantities of bromine in chlorine trifluoride is described. The liquid sample is allowed a vaporize, and the vapor is decomposed by passing through dry sodium chloride, the liberated chlorine being absorbed in potassium hydroxide solution. The mixture of sodium fluoride and chloride is dissolved in the hydroide solution and the whole diluted to standard volume. Chlorate and hypochlorite are reduced to chloride with sulfurons acid, and the bromide is oxidized a bromate by heating with sodium hypochlorite in buffered solution. Bromate liberates iodine from acidified potassium iodide solution, which is titrated with standard sodium thiosulfate solution using starch as indicator. Lower concentrations of bromine are determined absorptiometrically when the bromate in acid solution is used to oxidize 3-3 dimethyl naphthidine to the intensely colored meriquinonoid compound. The absorbancy of the solution is measured in Perspex cells. Neither method is specific for bromine, but interfering substances are unlikely to be present in chlorine trifluoride. (auth)
