This paper presents the results of the preparation of di(2-ethylhexyl)phosphoric acid (D EHPA)-impregnated Amberlite 2 200 resin and its application for the separation of Ni, V and Mo ions in sulfuric acid solution. The advantages of choosing this system are mainly due to the distinct metal ions ext

โฆ Synopsis
The reactions which aromatic sulfoxides may undergo in strong acids have been discussed in earlier papers of this series (1,2). The reactions may be summarized by the equations 1 and 2. 'Nhether equation 2 shows the correct stoichiometry

0-Deprotonation of 3 is, ofcourse, possible too. It is even more dominant than N-deprotonation for obvious reasons. It can be neglected, however, in this context, because 0 -deprotonation is a side-equilibrium which does not lead to the reaction product NzO.
## Abstract Alkali metal cations easily form complexes with proteins in biological systems; understanding amino acid clusters with these cations can provide useful insight into their behaviors at the molecular level including diagnosis and therapy of related diseases. For the purpose of characteriz
