Abstract: An environmental favorable spectrophotometric approach is proposed for the analysis of - iodine. The tactic includes oxidation of iodine to iodate, IO with bromine water and therefore the 3 liberation of free iodine from the iodate by addition of iodide in acidic medium pH 4 ± 0.2. The liberated iodine bleaches the pinkish red color of 2,8-dimethyl-3,7-diaminophenazine. The decrease in the intensity of the colour of the dye was measured at 530 nm. Beer's law is obeyed in the concentration range of 2-13 ?g of iodine. The molar absorptivity and Sandell's sensitivity of the 5 -1 -1 -5 -2 colour system in 1.90 x 10 l mol cm and 66.78 x 10 m were optimized and the method has been applied for the determination of iodine in tap water and soil. |
