Received 14 August 2016 ; Accepted 26 September 2016 Abstract The synthesis of copper NPS many routs ,thermal decrease , chemical decrease and metal vapour synthesis , radiation routes ,removal by laser . Electrolytic precipitation is one of the most suitable, simplest and low cost routes are using for broad range of materials.were put to produce copper nano utilized electrolytic routes . It could be possible to get onnano copper for large scale . They are properties by X-ray diffraction (XRD), scanning electron microscope(SEM).The morphology deposited structure of the nano copper powder prepared by electrolysis has dendritic shape.The particle size was decreased with additives and morphology of copper powder particles was changed from dendritic shape to cluster shape with presence of sodium sulphate and gelatin.

For example, one dimensional nanomaterial(tubes, wires, rods, etc.)is an important group of nanostructured with potential applications in electronics ,composite or sensor developments [1] .nanotechnology is the capacity to form nano-sized particles, for example nano powders, which are solid Nano powders can be utilized in most of the mentioned applications; it has been an interesting field [2].
The major interest has been focused on metal nanoparticles due to their bigger applications and special feature in varied fields.
Among various non-metal and metal particles, copper nanoparticles have attracted great attention due to of their catalytic, optical, and electrical conducting feature .For the synthesis of copper nanoparticles several routs were developed, thermal reduction, mechanical corrosion , chemical reduction, metal vapour prepare , radiation routs , laser ablation and micro emulsion techniques.In nanoparticle preparation, it is very significant to control the particle size, particle shape and morphology.prepared by mechanical chemical rout have decrease purity and wide particle size distribution.Gasevaporationrout display the costly raw material and complex equipment [3,6].Nanoparticles prepared electrolytic precipitation is one of the most suitable, simplest and decrease cost routs which are using for wide range of materials and properties [7].Therefore, in the current search , it was planned to output nano copper powder by utilized electrolytic precipitation from copper sulphate bath under suitable bath conditions [8] and as well as such as sodium sulphate and gelatin [9].

practical part
2.1.Electrochemical Synthesis:-Electrochemical or electro wining method was adapted to recover of the copper powder from commercial electrolyte solution containing more than approximately 25g/L of copper.Most suitable conditions to produce copper powder deposits were used in this work.

2.1.1.Production of Nano Copper Powder:
The recovery of copper powder from copper sulphate with H2SO4 solution was performed in the present research by using laboratory apparatus as shown in Figure

2.1.Characterization of copper powders[10,11]
The morphology and crystal structure of copper powders were examined by SEM (Fig. From figure (3-2) showed SEM images of nano copper powder obtained from electrodeposition (using lead sheet as anodes, current density at 14.7 A/dm 2 , distance between electrodes was 1.5cm).The images showed dendritic and cluster shape (diameter from 103 to 144 nm) as a characteristic of copper powder obtained from electro chemical method.

The addition of agents such as sodium sulfate (3g/l) and gelatin (0.05g/l) to the sample produced more fine particles with average diameters of 45 to 62 nm (Fig. 3-3).given practical conditions.The density of peaks reflects the high degree of crystallinity of copper nano particles.However, the different peaks are broad which specific that the crystallite size is low [12].

Conclusion
The results of this paper showed thattheelectro deposition method was useful to production of copper powder with nano size .At the same time the recovery of copper powder from copper sulphate with H2SO4solution could be possible to obtain nano copper powder.The morphology deposited structure of the nano copper powder prepared by electrolysis has dendritic shape.The particle size was decreased with additives and morphology of copper powder particles was changed from dendritic shape to cluster shape with presence of sodium sulphate and gelatin.
