Abstract

Iodide Ø¢ in samples Ø¢ containing Ø¢ magnesium Ø¢ fluoride Ø¢ was Ø¢ determinedØ¢  Ø¢ by using iodide selective Ø¢ electrode. Ø¢ Detecting Ø¢ the limit for iodide determination


was around Ø¢ 5x1 oآ·5Ø¢ Ø¢ M with a standard Ø¢ deviation Ø¢ ranged Ø¢ from Ø¢ Ø¢Â± 0.3 to آ± 0.6.


QuantitativeØ¢  Ø¢ methodsØ¢  Ø¢ including; standard Ø¢ additionØ¢  Ø¢ method, Ø¢ Potentiometric


titration Ø¢ by using a Gran plot paper for an equivalent Ø¢ point determination and a Ø¢ directØ¢  Ø¢ methodØ¢  Ø¢ wereØ¢  Ø¢ used Ø¢ for Ø¢ the Ø¢ analysis.Ø¢  Ø¢ DissolutionØ¢  Ø¢ of Ø¢ magnesium fluoride samples Ø¢ was investigated Ø¢ in various acids (HCI, HN03, HCI04, and H3P04). Good Ø¢ recovery Ø¢ of Ø¢ iodide Ø¢ was obtained Ø¢ by using Ø¢ hydrochloric and phosphoric Ø¢ acids Ø¢ for dissolution. Interference Ø¢ of Ø¢ uranyl Ø¢ ion and Ø¢ halide Ø¢ ions,


pآ·, cr,Ø¢ and Br- on iodide response was also studied. This method can be used


for the determination of iodide in magnesium Ø¢ fluoride obtained Ø¢ from uranium


metal production.
