Polarographic Determination of Palladium(II) in Rocks After Extraction with [5-(4-Dimethylaminebenzylidene)rhodanine] and Methyl Isobutyl Ketone
A sensitive and selective method for the determination of palladium(II) in mineral veins of quartz, a pegmatite rock from Campo Largo County, Parana State, Brazil, was investigated. After liquid-liquid extraction of Pd 2- from aqueous solution, pH 2.4, with [5-(4-dimethylaminebenzylidene)rhodanine]...
