phosphate, and cyanide contents were determined by colorimetric method. Results indicate the presence of sodium, calcium, sulphate, and phosphate. However, barium and cyanide were below detection limit. Secondly, there was a relatively higher proportion of calcium and sulphate than sodium and phosphate in its aquifer.

Cyanide Destruction Hypochlorite / Chlorine. Alternatively, hypochlorite ions can be produced by dissolving suitable salts, such as sodium or calcium hypochlorite, in water. Free cyanide reacts rapidly with hypochlorite (OCl) in aqueous solution to form cyanogen chloride, otherwise known as tear gas.

Potassium Sodium cyanide. The effects of both cyanide compounds are also identical. Ingestion of KCN or NaCN can cause headache, nausea, dizziness and nervousness. Extraction of gold can also be done using KCN through similar process. In this reaction, the resulting product is potassium gold cyanide (KAu (CN2)).
