چکیده
Abstract In this study, the silver extraction potential from waste x-ray films using sodium hydroxide and nitric acid was studied. Sodium of different concentrations were used as stripping solutions to determine optimum leaching concentration. Optimum time temperature also investigated by varying temperatures, respectively. The stripped analysed for concentration Flame Atomic Absorption Spectrophotometer. Results obtained revealed that, stripping, 26.6 mg kg −1 ion at an concentration, 1.5 M, 900 minutes 30 °C. For a maximum 9830.6 4 1,440 result that agent significant factor affecting recovery, with possessing much higher recovery rate compared hydroxide.

Recovery of Silver from Waste X-ray Film by Alkaline Protease from Conidiobolus Coronatus
The waste X-ray/ photographic films contain 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. Since silver is linked to gelatin in the emulsion layer, it is possible to break the same and release the silver using proteolytic enzymes. Alkaline protease from Conidiobolus coronatus was investig...

In this work, thealkaline roasting and sulfuric acid leaching processes were employed to extract vanadium from the magnetite ore of Saghand mine in central Iran. The response surface methodology based on the central composite design model was applied to optimize the parameters involved in the processes. The studied roasting parameters were temperature (900-1100 °C), sodium carbonate percentage ...

متن کاملRecycling of exposed photographic X-ray films and recovery of silver using Bromelain
In the present work an environmentally friendly recycling system to peel away the base coat from the X-ray film by using an enzyme was developed. Bromelain, a proteolytic enzyme extracted from the waste apex of pineapple was used for stripping the silver layer on the exposed film by hydrolysis of gelatin. The collected film can be reused for the manufacturing of X-ray film or other materials li...
متن کاملLeaching of gold, silver and accompanying metals from circuit boards (PCBs) waste
Au-Ag noble metal wastes represent a wide range of waste types and forms, with various accompanying metallic elements. The presented leaching strategy for Au-Ag contained in circuit boards (PCBs) aims at gaining gold and silver in the metallic form. Application of the proposed ammonium thiosulphate leaching process for the treatment of the above mentioned Au-Ag containing wastes represents a pr...
