The study of dissolution process showed that the palladium could be dissolved at 323Kin organic system which consisted of DMSO and one of the following solvents: 1,2-dibromoethane, tribromomethane, 1,1,2,2-tetrabromoethane or tetrabromomethane. As a result of the dissolution reaction in binary organic system, the square planar palladium( II) complexes were obtained. Products of the dissolution of metallic palladium were characterized using UV-Vis and IR spectroscopy, MS spectrometry, cyclic voltammetry and analytical methods.

Possibility of Some Metals Dissolution in Mixtures of Dimethyl Sulfoxide and Aliphatic Halogen Derivative. Part II. Characteristics of the Metallic Nickel Dissolution Reaction in Binary Organic Mixtures

Nickel can be dissolved at temperature 323 K in binary organic mixtures containing dimethyl sulfoxide and one of halogeno aliphatic derivatives: 1,2-dibromoethane or tribromomethane, 1,1,2,2-tetrabromoethane, tetrabromomethane and hexachloroethane. As a result of dissolution of metallic nickel in binary organic system the octahedral nickel(II) complexes were obtained. Products of the dissolution of metallic nickel were characterized by UV-Vis and IR spectroscopy,MS spectrometry, thermal decomposition and analytical methods.

The Influence of Steric Effect and Alkyl Chain Length on Extraction of the Complexes of Co(II), Ni(II), Cu(II), Zn(II) and Cd(II) with 1-Alkyl-2-methylimidazoles

Extraction of complexes of 1,2-dimethylimidazole, 1-ethyl-2-methylimidazole, 1-propyl-2-methylimidazole and 1-butyl-2-methylimidazole with Co(II), Ni(ii0, Cu(II), Zn(II) and Cd(II) from aqueous solutions (I=0.5 at 298 K) with benzyl alcohol was investigated. For each system, the composition of the extracted species, their partition constans and the pH1/2 were determined.
