Extraction Mechanism of Palladium With Didodecylmonothiophosphoric Acid in Heptane Diluent

Liquid-Liquid Extraction of Palladium (II) from Hydrochloric Acid Solutions by Dihexyl-Sulphide and -Sulphoxide

“…Palladium was stripped from the organic phase with 10 % dimethylamine. Concentration of palladium in aqeous solution was assayed by spectrophotometer 14) , after the addition of 1 % α -nitroso -β-naphthol in ethyl alcohol to aqueous solution adjusted to pH 1 with hydrochloric acid and 10 % sodium carbonate, palladium was extracted with toluene and then determined utilizing the maximal absorption at 370 nm. The concentrations of chloride and the water content in the organic phase were examined by Volhar's method with nitrobenzene and Karl Fischer titration respectively.…”

Aggregation equilibria of the components of the commercial extractants LIX 622 and LIX 622N in toluene and n-heptane

“…Extractants based on alkylsalicylaldoxime have been used for copper removal from different media [4][5][6]. The study of their aggregation equilibria in organic solvents is a necessary previous step in order to get a complete understanding of the metal distribution equilibria in biphasic systems.…”

Solvent Extraction of Palladium(II) with Various Ketones from Nitric Acid Medium

“…As a result, solvent extraction of palladium has been studied as a means of recovering this metal. [1][2][3][4][5][6]17] Various reagents have been studied on the solvent extraction of Pd(II), for example, trialkyl amines, [5,7] 7-substituted-8-hydroxyquinoline, [8,9] Schiff base, [10] and 1-phenyl-3-methyl-4-benzoylpyrazolone-5-one (HPMBP). [11] Sulphurcontaining extractants are known as highly selective extractants for Pd(II).…”
