Title: Detemination of Iodate in Indized Salt by I_3~- Spectrophotometric Method
Abstract: A new type of spectrophotometric determination of IO~-_3 in iodized salt has been established.The maximum absorbance is measured at 350nm with the molar absorbity of 8.24×10~4(L/mol·cm). and Lamber-beers law is obeyed if I content ranges from 2ug to 60ug.The relative standard deviation is 2.63%,and the recovery ratio is from 96.69% to 102.3%.The method is simple and rapid.
