چکیده
Humans first used copper about 10,000 years ago. A copper pendant discovered in Northern Iraq is thought to date back to around 8700 BC. Prehistoric man probably used copper for weapon making. Ancient Egyptians too seemed to have appreciated the corrosion resistance of the metal. They used copper bands and nails in ship building and copper pipes were used to convey water. Some of these artifacts survive today in good condition. An estimate of the total Egyptian copper output over 1500 years is 10,000 tons.

Investigation of corrosion protection properties of TiO2-CdO nanocomposite coating prepared by sol-gel method on copper
the Sol–gel nanocomposite coatings have been investigated for copper metal as a potential replacement for the hazardous and banned hexavalent chromate conversion coatings. TiO2–CdO nanocomposite thin films were deposited on copper using the sol–gel method. The sol-gel coatings were prepared using a sol obtained by the hydrolysis and condensation of tetra-o-butyl titanate. They were doped with c...

The main aim of this research is to determine optimal leaching conditions; Eh, pH and complexing agent concentrations, for recovery of Copper from hydroxide sludges such as those produced by electroplating shops, metal finishers, treatment of acid mine drainage, and industrial wastewater in general. This has been preceded by a theoretical approach and numerical and computer calculation. Pot...
متن کاملCorrosion Protection of Copper by TiO2 Nanoparticles and SN Schiff base Coating
The corrosion protection abilities of modified copper in 2-[((Z)-1-{6- [(2-sulfanylphenyl)ethanimidoyl]-2-pyridyl}ethylidene) amino]-1- benzenthiol solution containing TiO2 nanoparticles were evaluated by Tafel polarization and impedance spectroscopy in 3.5% sodium chloride solution. The samples were characterized by energy dispersive X-ray (EDX) and scanning electron mi...
متن کاملExtraction of Traces of Copper as Tetra-Butylammonium Tetrathiocyanato Copper (II) and Its Spectrophotometric Determination Using Eriochrome Black T
An extraction-spectrophotometric method for the determination of traces of copper (II) is described. The method is based on the quantitative extraction of copper as tetrabutylammonium tetrathiocyanato copper (II) into methyl isobutyl ketone, followed by spectrophotometric determination, using eriochrome black T as a metallochromic indicator. The red-violet mixed complex of copper absorbs at...
متن کاملExtraction-Fluorimetric Determination of Low Levels of Copper by 1,7- Diaza-15-Crown-5 and Rose Bengal
A simple and sensitive extraction-fluorimetric method for the determination of copper is reported. The 1,7-diaza-15-crown-5-copper-rose Bengal (DA15C5-Cu-RB) ternary complex is quantitatively extracted into chloroform, diluted with ammoniacal acetone and its fluorescence intensity is measured at 570 nm with excitation at 540 nm. A linear calibration graph was obtained over the copper concen...
