Extraction of phosphorus and metal contaminants from aged commercial three-way catalysts by using weak organic acid solutions

The developed procedure consists of the use of weak organic acid solutions (citric, oxalic acid) at a low temperature (T=50ºC) to remove phosphorous and other metal contaminants (e.g., Pb, Fe, Cu, Ni, Cr) from a commercial TWC.

The potential application of the described process is to permit the extraction of metal poisons from aged three-way catalytic converters in an easy and cheap way, and also from similar commercial catalysts the deactivation of which is also due to metal deposition.
