- X-ray films
have two essential components –
• Base- Polyester (polyethylene terephthalate resin) 0.2mm thick.
• Emulsion- Silver halide crystals suspended in gelatin.
recycles all x-ray film and captures silver for recycling from their
silver recovery units.
- An industrial
process for X-ray film-recycling was worked out by the IPR-company9
and introduced to the market under the name REPET on the basis of a
· availability of the waste chips on a repetitive basis
· suitable purity
· very competitive price.
- When an X-ray
film has been exposed, it must be processed in order to produce a
permanent visible radiographic image that can be kept without
deterioration for a number of years.
- 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.
included investigations concerning optimal parameters of leaching
process for treatment of exposed X-ray films, such as temperature,
time, acid concentration and solid/liquid ratio. Investigations on
valorisation of silver from exposed X-ray films started with onset
with photo techniques.
- X-ray film
processing in medical applications represents a significant
opportunity for new technologies to reduce or eliminate water use.
One of those technologies is the application of water recycling to
the process equipment.
- X-ray film
processors are used throughout the medical industry by doctors,
hospitals, imaging centers, health and medical clinics,
chiropractors and veterinarians.
