COMPARATIVE STUDY OF THE DETERMINATION OF AMINOGUANIDINE BICARBONATE BY IODOMETRY AND PHOTOMETRY

A comparative study demonstrated that both the iodometry and photometry could be used for the determination of aminoguanidine bicarbonate.The iodometry was easy to operate and spent less analysis time and had a better precision,compared to the photometry.RSDs of the analytical results,which were separately obtained by the analysis of the same sample (n=9) using iodometry and photometry,were 2.8% and 0.54% respectively.
