Researchers from the Institute of Molecular Science (ICMol) of the University of Valencia (UV) are taking part in REMADYL, a Horizon 2020 European Project consisting in developing scavenger materials for the removal of lead stabilizers from End-of-Life PVC.
Firstly, the UV successfully developed a lab scale synthesis to obtain a precursor material for supporting the species directly responsible for the scavenger of the lead, based on called Layered Double Hydroxides (LDH). This precursor material consists of layers of divalent and trivalent metal cations with an interlayer space that can be occupied by different size anions.
Recently, the researchers from the University of Valencia have successfully optimized a semi-pilot synthesis to obtain the LDH precursor material at a larger scale. The group has obtained the ZnAl-LDH batch at large scale in an equipment as the one shown in the Figure. Afterwards, the researchers are focusing in obtaining the final material for removing the lead.
Equipment developed to carry out synthesis at large scale.
