is highly soluble and stable in alkaline rather than acidic solutions, the Harvard team paired it with a quinone compound that is soluble and stable under alkaline conditions, in contrast to the acidic environment of their original battery developed last year.
Hexacyanoferrates (Table 1, complexes 9-10) show reactivity comparable to that of aminoprusside ion but in the presence of chitosan the equilibrium in the former case is shifted to formation of iron(II/III) ferrocyanide
that indicates chitosan role as a dispersant ,
Union Showa, under the guidance of Professor Mimura of Tohoku University, has successfully established a new method of stable solidification by heat treating mixture of used ferrocyanide
and zeolite under a non-reducing atmosphere in which vaporized Cs by thermal decomposition of insoluble ferrocyanide
is trapped again on the high surface area of zeolite.
Monitoring with ultraviolet-visible spectrophotometry showed the solution was reduced at a relatively constant rate and that each ferrycyanide molecule was reduced to one ferrocyanide
By using three types of enzymes, the quantity of pyrophoric acid is converted to an equivalent quantity of potassium ferrocyanide
, an electron mediator, making measurement of the oxidation current possible, a world-first achievement.
in the presence of oxygen and protons can be oxidized to regenerate ferricyanide and produce water as the by-product.
2] and identification of the ferrocyanide
binding site in Hb.
May also contain: mica, iron oxides, yellow 5, red 7, red 6, ferric ferrocyanide
, aluminum powder.
The researchers produced the patterns in a thin, transparent gel continuously fed with a fresh solution containing sulfuric acid and iodate, sulfite, and ferrocyanide
The expected histochemical products in this reaction are cupric ferrocyanide
(Karnovsky's precipitate) and cuprous thiocholine iodide (resulting from the reduction of ferricyanide and cupric ions by thiocholine).
Excised protein spots were destained in a 1:1 mixture of 30 mM potassium ferrocyanide
and 100 mM sodium thiosulfate.
Other complicating factors led Rees to return to the problem until he had developed a more comprehensive method for identifying albumin that involved potassium ferrocyanide
and mercury perchloride, in addition to the traditional tests.
