Quaternary relief evolution of various volcanic areas in Hungary has been determined by (a) the original volcanic succession and related, primary landforms and (b) the subsequent postvolcanic tectonism and erosion. This overview presents some details of these processes through selected relief types from the Miocene volcanic mountains of Hungary: the High Börzsöny erosional caldera rim, the Rocks of Vadálló-kövek, the Dobogókõ Ridge, the Danube Bend area, and the badlands and fairy chimneys of the southern foreland of the Bükk Mts, by showing different volcanic relief types, and postvolcanic tectonic, paleogeographic and erosional history. In the Quaternary, the tectonic transformation of these and other volcanic areas has been highly variable; in contrast, erosional processes of the Quaternary, i.e. pedimentation, loess and other eolian sedimentation, derasion, periglacial relief formation, and channel erosion, have affected almost all areas in Hungary; hence types and rates of erosion can be well constrained.

Quaternary pyridinium aldoximes have been analyzed by thin-layer chromatography. Their separation was adequate when silica plates were used with a mobile phase with a high water content. As a consequence of their limited migration, reversed-phase TLC was not appropriate for determination of the lipophilicity of quaternary pyridinium aldoximes. Displacement TLC of some quaternary pyridinium aldoximes is, nevertheless, possible using silica as stationary phase with water-acetone-hydrochloric acid mobile phases. Normal-phase TLC with different concentrations of organic modifier gave a series of R M values for the pyridinium aldoximes. Approximation of the different plots of R M against organic modifier concentration to straight lines afforded R M,0 values and the slopes of the lines. The R M,0 values and the slopes both serve as indicators of the hydrophilic character of the compounds.

Abstract  

The extraction of Np(IV), Pu(IV) and U(VI) from aqueous hydrochloric acid into quaternary amines has been studied. The dependence of the distribution coefficient on amine concentration suggests that the actinide ions extracted are NpCl 6 2− PuCl 6 2− and UO2Cl 4 2− . This is further supported by the absorption spectra of the amine extracts of these actinide ions. Based on the extraction data obtained, a simple method for the separation of typical metal ions such as Cs, lanthanides and Zr from U(VI) and Pu(IV) is suggested.
