Iodometric microdetermination of semicarbazide by amplification reactions

An analytical method for the determination of 10–2000 μg of semicarbazide is described, using titrimetric procedure with an amplification reaction. It relies upon the reaction of semicarbazide, in phosphate-buffer (pH 7) solution, with a chloroform solution of iodine, and removal of its excess; oxid...

Description
Summary:An analytical method for the determination of 10–2000 μg of semicarbazide is described, using titrimetric procedure with an amplification reaction. It relies upon the reaction of semicarbazide, in phosphate-buffer (pH 7) solution, with a chloroform solution of iodine, and removal of its excess; oxidation of the iodide formed with bromine; and determination of the liberated iodate by the Leipert amplification procedure. The recovery ranged from 97.0 to 100.1%.
