Potassium dicyanoaurate Wikipedia

Potassium gold cyanide can be used for photoreduction of gold ions by nanopowder ZnO, preparation of gold-gold junction electrodes in voltammetric glucose detection, and other reactions where metallic gold is prepared. There is a trivalent compound, potassium tetracyanoaurate(III), K[Au(CN) 4], but its use is less common.

Potassium cyanide Wikipedia

Potassium cyanide is a compound with the formula K CN.This colorless crystalline salt, similar in appearance to sugar, is highly soluble in water. Most KCN is used in gold mining, organic synthesis, and electroplating.Smaller applications include jewellery for chemical gilding and buffing.. Potassium cyanide is highly toxic.The moist solid emits small amounts of hydrogen cyanide due to

Electrochemical preparation of potassium gold cyanide

depends on the purity of the gold salt used in the preparation of the bath. Be it an acid, neutral phosphate, citrate or alkaline cyanide gold plating bath, potassium gold cyanide (PGC) is the starting material. It is therefore important that pGc used for preparing plating baths must be very pure.

Electrochemical preparation of potassium gold cyanide

May 01, 1984· The essential requirements for the industrial preparation of potassium gold cyanide (pgc) are: (a) high rate of dissolution and (b) smooth and uniform dissolution. Employing galvanostatic and potentiostatic polarisation data and observations on the surface topography of anodes dissolved by both the techniques, it is shown that potentiostatic dissolution of gold in potassium cyanide at

Effect of Potassium Cyanide on Gold & Metals

The discovery that metallic gold is soluble in potassium cyanide came after studying the action of cyanides on plates of gold, and announced that they were slowly dissolved. Metallurgists pointed out that gold-leaf is dissolved by a dilute solution of the salt, and also showed that if the gold floats on the surface of the liquid, so that one side of the leaf is in contact with the air, while

Potassium Cyanide an overview ScienceDirect Topics

No signs of cyanide poisoning were observed; the gold concentration in whole blood was reported as 6011 μg/L 13 h after the ingestion, and the 24-h urinary gold was 429 μg/L (Wu et al., 2001). Similarly, in case of suicide by ingestion of gold potassium cyanide (2 g gold), it was concluded that effects were due to gold rather than to cyanide
