Potentiometric determination of iodide in magnesium fluoride by iodide electrode

الملخص EN

Iodide in samples containting magnesium fluoride was ' by using iodide selective electrode.

Detecting the limit for iodide determination was around 5x10 M with a standard deviation ranged from ± 0.3 to ± 0.6.

Quantitative methods including; standard addition method, Potentiometric titration by using a (؛ran plot paper for an e؟uivalent point determination and a direct method were used fol' the analysis, dissolution of magnesium fluoride samples was investigated in various acids (HCl, HNO3, HC104, H3P04).

Good recovery' of iodide was obtained by using hydrochloric and phosphoric acids for dissolution.

Interference of uranyl ion and halide ions, F\ Cl”, and ^٢" on iodide response was also studied.

This method can be used for the determination of iodide in magnesium fluoride obtained from uranium metal production.
