The reaction of copper (II) ethylenediamine-tetraacetate with cyanide ion

Reversible luminescent reaction of amines with copper(I) cyanide.

Copper(i) cyanide exposed to various liquid or vapor-phase amines (L) at ambient temperature produces a variety of visible photoluminescence colors via reversible formation of amine adducts. The adducts show phase matches to authentic (CuCN)L(n), n = 0.75-2.0, produced by heating CuCN with liquid amine.

The reaction of cytochrome oxidase with cyanide.

The ability of cyanide to inhibit the oxygen consumption of biological systems has long been known (cf. (4, 13)). Warburg (12, 13) appears to be the first to suggest that this action of cyanide was due t,o its combination with the ferric form of the enzyme, called by hi the Atmungaferment and later called cytochrome oxidase by Keilin and Hartree (5). In this paper we make use of this reaction o...

Reaction between hydrocyanic acid, cyanide ion and ferricytochrome c.

The speciation of copper (II)/ethylenediamine/oxalate system by evolving factor analysis

Principal component analysis and evolving factor analysis were applied to the study of the speciation of Cu (II)/ethylenediamine/ oxalate. Two programs were designed, based on mathematical algorithms. Error functions were calculated for evaluating the number of species. Submatrix analysis plots were constructed to estimate the species present in the system. The method should prove useful in stu...

Cyanide reaction with ninhydrin: elucidation of reaction and interference mechanisms.

A new sensitive spectrophotometric method has recently been developed for the trace determination of cyanide with ninhydrin. Cyanide ion was supposed to act as a specific base catalyst. Nevertheless, this paper demonstrates that the reported assay is based on a novel reaction of cyanide with 2,2-dihydroxy-1,3-indanedione, which affords purple or blue colored salts of 2-cyano-1,2,3-trihydroxy-2H...
