Zinc hexacyanoferrate

In strongly acid solution the reaction proceeds from left to right, but is reversed in almost neutral solution. Oxidation also proceeds quantitatively in a slightly acid medium in the presence of a zinc salt. The very sparingly soluble potassium zinc hexacyanoferrate(II) is formed, and the hexacyanoferrate(II) ions are removed from the sphere of action ... [Pg.399]

Zinc hexacyanoferrate was supported on the surface of Ti(IV) oxide grafted on a silica gel [476]. Electrochemical behavior of this electrode was dependent on alkaline metal cations and acetate anion concentrations. [Pg.755]

Electrochemical and electrocatalytic behavior of zinc hexacyanoferrate directly formed on Zn electrode [478] and on carbon substrates [479] were studied. [Pg.755]

Shown here are typical compositions of two highly active catalysts, one based on zinc hexacyanoferrate(II, III) and the other on zinc hexacyanocobaltate( III) ... [Pg.226]

Potassium hexacyanoferrate (III) -p-phenetidine test Potassium hexa-cyanoferrate(III) oxidizes p-phenetidine (4-ethoxyaniline) and other aromatic amines slowly with change of colour and the formation of potassium hexacyano-ferrate(II). If the hexacyanoferrate(II) formed is removed by zinc ions as the sparingly soluble, white, zinc hexacyanoferrate(II), the oxidation proceeds rapidly the white zinc hexacyanoferrate(II) is deeply coloured by the adsorption of the coloured oxidation products.

A solid-state potassium-selective electrode based on potassium zinc hexacyanoferrates, K2Zn3[Fe(CN)6]2. ion exchanger is described [472]. The sensor can be used in the determination of K+ ion in concentration range 10 — 1 M KCl. [Pg.755]
