چکیده
The alloys of copper find extensive use in automobile radiators, heat exchangers, home heating systems and panels for absorbing solar energy. Copper (II) is a biologically active metal; its compounds affect the vital activity of plant and animal organisms. Copper is one of essential elements required for normal human metabolism [1]. Copper (II) is known to play a significant role in biological systems and also as a pharmaceutical agent [2]. Its antibacterial properties have been known for thousands of years. Synthetic copper(II) complexes have been reported to act as a potential anticancer and cancer inhibiting agents and a number of copper complexes have been found to be active both in vitro and in vivo [3,4]. Therefore it is necessary to control that the content of copper (II) ions in the environmental objects is within the permissible concentrations.
