Gf. Nichugovskii, COULOMETRIC DETERMINATION OF MACROCONCENTRATIONS OF WATER WITH FISCHERS REAGENT, Russian journal of applied chemistry, 67(1), 1994, pp. 126-127
A new hybrid method for determination of water by Fischer's reagent ha
s been suggested, which involves preliminary gravimetric titration wit
h crystalline iodine and subsequent direct or reverse coulometric titr
ation of water residue or excess iodine. AIL operations are conducted
in a coulometric cell with separated electrode spaces. The method make
s it possible to determine moisture contents of up to 100%. Relative e
rror of the analysis does nor exceed +/-5%.
