Selective separations by reactive ion exchange: Part 4. Preconcentration of cadmium and zinc by in situ precipitation as hexacyanoferrate(II) salts on gel and macroporous ion-exchange resins
TL;DR: In this paper, the in situ precipitation of traces of cadmium(II) and zinc (II) ions as hexacyanoferrates from aqueous matrices was studied on conventional polystyrene gel and macroporous cation-and anion-exchange resins.

Photochemistry of co-ordination compounds—XV: Cyanide complexes☆
TL;DR: In this paper, the photochemical behavior of some cyanide complexes has been investigated at various wavelengths, with particular reference to irradiation in the ligand field spectral region, and a reaction mechanism involving a primary photoaquation reaction was proposed.

Analysis for chromium traces in natural waters. I. Preconcentration of chromate from P.P.B. levels in aqueous solutions by ion exchange.
TL;DR: A new procedure for the preconcentration of p.p.b. concentrations of chromate from aqueous solutions has been developed, producing very high concentration factors.

Acute toxicity to fish of solutions containing complex metal cyanides, in relation to concentrations of molecular hydrocyanic acid
TL;DR: In this article, indirect evidence indicating that the toxicity of solutions of complex metal cyanides to fish is a function of the concentration of molecular (not ionized) HCN is reviewed, and it is shown conclusively that this factor virtually alone determined the acute toxicity to bluegills of various solutions of simple and complex cyanides.

Determination of manogram quantities of simple and complex cyanides in water
TL;DR: The method avoids the extraction step which was pre viously necessary under 0.2 mg CN/1, avoids errors due to HCN gas evolution losses, is easy to manage, not prone to trouble and suitable for the continuous moni toring of waste-water streams or for controlling cyanide detoxification methods.
