Iodometric microdetermination of hydrazines by amplification reactions.

摘要: Abstract Two new, simple, rapid, and accurate iodometric amplification methods are described for the micro submicro determination of hydrazine. The first depends on oxidation with a chloroform solution iodine removal its excess, resulting iodide bromine, titration liberated iodate. second method is based periodate at pH 8, masking excess molybdate 3, order involved in two 6- 3-fold, respectively. Micro amounts hydrazine sulphate dihydrochloride were determined satisfactorily by both methods, average recoveries being 98·6 99·4%.
