Abstract

Un résidu contenant un catalyseur de métaux lourds obtenu par une usine de production d'acide polycarboxylique aromatique est traité, de préférence, à l'aide d'ions de carbonate/bicarbonate. Ce procédé assure la dissolution de sensiblement la totalité du résidu dans un milieu aqueux, et la précipitation des catalyseurs de métaux à partir de la solution.
