Abstract
Silver is powerful natural antibiotic noble metal has been used for thousands of years with no harmful side effect since have being observed , Today colloidal silver is rapidly gaining favor in the medical community and water treatment reflecting a kind of revival in the public health community sector. In this research three technique and the most efficient one was the arc discharge technique ,we design colloidal silver (CS) generator using two rods of silver connectedly to pulsed DC high power supply to get arc discharge caused evaporate silver rods which immersed in water. Later, we made improvement on this design by using DC . Power supply with high purity silver. Rods arranged in certain arrangement then we get many silver water samples according to different parameters. In order to determined physical properties of (CS) solutions, AFM. UV. Visible spectrometry, AAS, and electrical conductivity were applied to each samples. The results show (CS) generator(method B) is effective tool to get narrow range nano- colloidal silver water suspension with size distribution (40 - 560) nm , color of each solution is characterized to particle size silver particle - ionic solution . The electrical conductivity of sample depended on the ionic - particle silver concentrations (10-32) p .p. m
