ABSTRACT: This works aims at preparing at room stable Na2FeO4 and tracking its degradation over time. The
synthetic, during this step, was carried out by electrochemical method. The latter was given maximum focus because of its simplicity
and the high degree of purity of the resulting product with respect to wet and dry
method. This paper reviews the development
of the electrochemical method applied to the synthesis of stable at room Na2FeO4,
optimizing the parameters impacting the performance of the oxidation of iron(II)
in to iron(VI) in alkaline NaOH, saturated at a temperature of 61°C and a current
density of 1.4 A/dm2, in order
to simplify the synthesis process, to minimize the cost and to improve the production
of iron(VI) to meet the growing demand of ferrate(VI) useful for water treatment.
The supervision of the degradation of synthesized Na2FeO4 shows its stability over a period of 10 months, which makes storage and transport
easier. The phases obtained were characterized
by IR spectrometry, X-ray, M?ssbauer, spectroscopy and thermogravimeric analysis.
