New extractants for separation of platinium-group metals from chloride solution...
Paiva, A. P.; Carvalho, G. I.; Schneider, A. L.; Costa, Maria Clara; Costa, A. M.; Assunção, A. F.; Nogueira, C. A.In this paper some results on the application of four N,N’-tetrasubstituted malonamide derivatives for the extraction and separation of platinum-group metals (PGMs) are presented. The above mentioned extractants were specifically synthesized in order to evaluate their efficiency for the extraction of a specific metal, or group of metals, from aqueous chloride matrices. Different behaviours were obtained towards...
