T. Sinner et al., INFLUENCE OF FREEZING OF AQUEOUS SAMPLES ON THE FE(II) FE(III) EQUILIBRIUM/, Fresenius' journal of analytical chemistry, 349(4), 1994, pp. 334-335
The influence of freezing of aqueous samples on the Fe(II)/Fe(III) equ
ilibrium has been investigated by ion chromatography. No change has be
en observed in the pH-range 2-5, irrespective of the freezing temperat
