Water is one of the most important compounds for existence nature and human life. Nowadays, as a result increasing industrialization industrial production, heavy metals pollute clean water resources. Copper (II) ions are leading in industry. There high proportion copper especially production printed electrical electronic circuit, paper silicon synthesis, wood preservation, fertilizer oil refini...

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. potenti...

In plants, copper is an essential micronutrient required for photosynthesis. Two of the most abundant copper proteins, plastocyanin and copper/zinc superoxide dismutase, are found in chloroplasts. Whereas plastocyanin is essential for photo-autotrophic growth, copper/zinc superoxide dismutase is dispensable and in plastids can be replaced by an iron superoxide dismutase when copper is limiting....

Despite increased interest in the role of copper deficiency in clinical problems and an increased understanding of the physiological roles of copper, the diagnosis of a marginal deficiency has not been perfected. The use of non-standardized procedures and the effects of factors other than copper nutriture have impeded identification of the "ideal" indicator of copper nutritional status in adult...

Copper is essential but can be toxic even at low concentrations. Coping with this duality requires multiple pathways to control intracellular copper availability. Three copper-inducible promoters, controlling expression of six copper tolerance genes, were recently identified in Escherichia coli. The cue system employs an inner membrane copper transporter, whereas the cus system includes a tripa...

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 concentrat...

Copper and its alloys are extensively used in marine applications due to high corrosion resistant behavior. But the immunity of copper varies with environmental factors especially sea water ingredients. Many researchers investigated level materials different oceans/seas. Unfortunately, such study is missing Bay Bengal water. Moreover, inclusion alloying elements can have influence on behavior c...

1. Copper compounds (calcium copper edetate, copper heptanoate, copper methionate, copper chloride, copper oxide, dicopper oxide and copper gluconate) are normally used, orally in feed or in an injectable solution, to treat copper deficiency in food-producing animals. In veterinary medicine, the recommended doses are 50 to 100 mg copper per animal given as a single injection. Copper has antimic...
