Extraction of Silver From Photographic Waste
The waste photographic films/X-ray contains 1.5 2 % (w/w) black metallic silver which is recovered and reused. Around 18-20% of the world's silver needs are supplied by recycling photographic waste. Silver is a precious metal, further silver has wide uses like in jewellery, dentistry, photography, mirrors, optics, industries, etc. So the recovery of silver is beneficial in industrial, chemical ...
متن کاملSynthesis of Silver Nanoparticles from Spent X-Ray Photographic Solution via Chemical Rreduction
Silver metal was recovered primarily from spent X-ray photographic solution using a horizontal tube furnace. The X-Ray Diffraction (XRD) spectroscopy analysis approved almost 95 percent purity of the recovered silver metal. In the next step, the synthesis of silver nanoparticles from the recovered silver metal proceeded by using chemical reduction method. The proposed method uses e...
متن کاملReclaiming academia from post-academia.
I s nanoscience the “first full embodiment of post-academic science”? Have many of the traditional core values of publicly funded university science been eroded to the point where they are now “part of a scientific mythology”? And is it “morally bankrupt” to draw a distinction between ‘pure’ and ‘applied’ science? These claims, which were all made in a recent commentary in Nature Nanotechnology...
متن کاملSilver Colloid Particles Preparation by Using Photographic Development System
The colloid silver sols with defined average particle size were prepared by means of chemical reduction of silver compound [Ag(SO3)2] 3– by several organic redox systems used as development agents in photography. The average size of the particles varied from 700 to 150 nm in dependence on sulphite concentration in reaction system and reduction compound type.
متن کاملA Novel Silver Recovery Method from Waste Photographic Films with NaOH Stripping
Silver, one of the precious and noble metals, is used in large quantities for many purposes, particularly in the photographic industry. It has been reported that 25% of the world’s silver needs are supplied by recycling and that 75% of this is obtained from photographic waste. For this reason, the methods applied to recover silver from photographic waste are important in reducing cost and time,...
