Abstract : A polarographic method has been developed for determining zinc in additives DF-11, DFTs-3/8, LANI-317, VNIINP-354, and VNIINP-360. The zinc is extracted from the solution of the additive in hexane by a 6N aqueous HCl. This method allows the content of zinc to be determined in the specimen in 25 to 30 minutes, or with series analysis in as little as 15 to 20 minutes. (Author)
