preparation of sodium cyanide standard solution

How to Prepare and Storage of Cyanide Solution

02/11/2016  How to Prepare and Storage of Cyanide Solution. The cyanide is usually dissolved in a little water before being added to the stock solution, as the amount of KCy present is more easily determined in a strong solution than in any other form. A special dissolving vat of small size is often provided and is placed at a higher level than the large vats ...

6 Sulfides and sulfites as well as other reducing substances, inorganic cyanides and isonitriles: Stir into sodium hypochlorite solution (Cat. No. 105614) and, if necessary, leave to react for several days. Caution: some substances may show a violent reaction! Draw off any toxic or flammable gases that may be formed. Excess oxidant should be neutralized with sodium thiosulfate (Cat. No. 106513).

Hence, these films require annealing before the final solar cell device is completed. The stoichiometry may be improved by annealing in a Se ambient or by etching in cyanide solutions to remove excess Se and Cu. Electrodeposition as well as electroless deposition could be used for the preparation of precursors for CIGS solar cells [93,94]. Electroless deposition takes place via redox reactions without
