I have attached one example for this extraction done with Polycarbonate plastics. Can I adopt the procedure for the other plastic polymers (mentioned above)? Or are there any other constraints I have to look after?
Dear Mahamuni: The quick answer is no. The polymers you mention are quite different, therefore solubility parameters are different too. I suggest to look for the polymer handbook, solvents and non-solvents section, and look for such data for each polymer you are interested into. You may be surprised.
Thanks Prof. Ponce. I do collecting information on that, and i met with a good work done by Achilias et al (DOI 10.1007/s00289-009-0104-5) with the aid of dissolution and reprecipitation technique. they done this work for recycling purpose. but how can extract my Bisphenol A from the dissolved content. BPA is soluble in water, methanol, acetonitrile and acetone. can you clarify it please?
Have you tried ultrafiltration under vacuum? Use 3 kDa (or other appropriate pore size) filter. You should be able to separate the low MW compounds such as BSP A from the polymeric compounds (PE, PP, PET etc.)
Selective extraction. You shall find what solvent is good for BPA, not being good for the polymer matrix. Temperature must be carefully watched.
