Abstract
Iodide in samples containing magnesium fluoride was determined by using iodide selective electrode. Detecting the lim it for iodide determination was around 5x 1 o·5 M with a standard deviation ranged from ± 0.3 to ± 0.6. Quantitative methods including; standard addition method, Potentiometric titration by using a Gran plot paper for an equivalent point determination anda direct method were used for the analysis. Dissolution of magnesium fluoride samples was investigated in various acids (HCI, HN03, HC104, and H3P04). Good recovery of iodide was obtained by using hydrochloric and phosphoric acids for dissolution. Interference of uranyl ion and halide ions, p-, cr. and Br- on iodide response was also studied. This method can be used for the determination of iodide in magnesium fluoride obtained from uranium metal production.
