Design And Implementation Of Spectrophotometry For Iodine Determination Based On Flow Injection Analysis
Journal Title: IOSR Journal of Research & Method in Education (IOSRJRME) - Year 2018, Vol 8, Issue 2
Abstract
Iodine is an element nonmetal and essential micronutrient needed by human body in a trace amount, iodine deficiency may cause brain damage, mental retardation, cretinism and endemic goiter (GAKI). Analysis method of detecting iodine has widely been used, where iodometry and spectrophotometry analysis is a standard method to determine iodine content. The analytical performance of iodine determination with a sensitive and selective flow injection analysis had been developed and evaluated. Iodate reacted with the excessive iodide in an acid medium to form tri-iodide, which can be detected with spectrophotometer at 352 nm. The result of analytical performance evaluation of that developed method indicated a linearity of calibration curve at the range of 0.1-1.0 mg/L, with the R2 value approached one and detection limit is 0.01 mg/L. Through the flow injection analysis method, the precision of iodine determination was evaluated, which was revealed as 0.08% variant coefficient for the concentration of 0.5 mg/L. This method have been successful developed for the iodine determination in iodized sample.
