COPPER SULPHATE FROM COPPER ASH

Copper sulphate is a well known compound of copper. The commercial name of this compound is Blue Vitriol. Blue stone or chalcantihite. Copper sulphate is used in copper plating, as a mordant in dyeing, as a laboratory reagent, in electric batteries, in production of others salts, as germicide and insecticide in leather industry pulp in pigments in the preservation of wood, pulp and ground pulp in the process of engraving and lithography in ore flotation, destroying large and low roms of animal life from drinking water, in petroleum industry synthetic rubber, steel manufacture etc.

Various forms of copper sulphate are available in the market are present. These forms are classified according to this water if crystallization of copper sulphate anhydrous copper sulphate is blue coloured powder. From commercial point of view copper sulphate has the great importance of all copper chemicals based on tonnage alone.

The manufacturing of copper sulphate is also well known from a very long period. At present this compound is being manufactured from copper metal and sulphuric acid reaction.

Copper sulfate is an algaecide, bactericide, and fungicide. When it is mixed with calcium hydroxide it is known as Bordeaux mixture.1 The International Union of Pure and Applied Chemistry (IUPAC) name for this active ingredient is copper (2+) sulfate or copper (II) sulfate. Other names include copper (2+) tretraoxidosulfate or copper (II) tretraoxidosulfate.

Formulations include basic copper sulfate, copper sulfate monohydrate, copper sulfate pentahydrate and copper sulfate anhydrous. Their Chemical Abstracts Service (CAS) registry numbers are 1344-73-6, 1332-14-5, 7758-99-8, and 7758- 98-7, respectively. Pesticides containing copper sulfate monohydrate and/or copper sulfate anhydrous have been cancelled by the United States Environmental Protection Agency (U.S. EPA).

Copper sulfate has been used in the United States since the 1700s, and it was first registered for use in the United States in 1956. The U.S. EPA completed the reregistration of copper sulfate in 2009.3 See the text box on Laboratory Testing.

Copper sulfate is an inorganic salt that is highly soluble in water. The copper ion is the component of copper sulfate with toxicological implications.

Copper is an essential mineral, and the recommended dietary allowance of copper for human adults has been set at 900µg/day.

Copper is also a ubiquitous element. It can be found in the environment and in foods and water.
