STUDY ON THE COMPLEX FORMATION BETWEEN N-PROPYLSALICYLIDENE BASED ON SILICA AS ION EXCHANGER AND SOME TRANSITION METAL IONS
N-propylsalicylidene based on silica as ion exchanger (IE) was used for the separation by complexation of Mn2+, Co2+, Ni2+, Cu2+, Hg2+, Cr3+, Fe3+, and UO22+ from their parent solutions. IE and its metal complexes are characterized by elemental analysis, electronic and infrared spectra, in addition to thermal analysis in atmospheric pressure. The mode of chelation and the proposed geometric str...
متن کاملSolvent enhanced ion chromatography of alkaline earth and transition metal ions on porous monolithic silica
The high-performance separation of alkaline earth and transition metal ions on a bare porous silica 10.0 cm× 0.46 cm monolith (Merck Chromolith Si) was achieved using solvent enhanced ion chromatography. Using acetonitrile or methanol based ammonium and sodium acetate buffered mobile phases, the effect upon cation retention of mobile phase ionic strength, organic content and pH were evaluated. ...

متن کاملStrontium ions as a probe for the role of alkaline-earth metal ions in histamine secretion [proceedings].
granule-membrane surface as it undergoes exocytosis is dramatically decreased (Howell & Tyhurst, 1977). Incubation of isolated granules with 1-2m~-CaCI, did not produce a visible decrease in the number of anionic sites, although as shown by Dean (1974), even the small decrease in charge which could be expected after addition of 1 mM-CaZ+ would be sufficient to produce a 50-fold increase in the ...
متن کاملOptimization of Continuous Flow Adsorption of Heavy Metal Ions on Continuous System Column by Peganum Harmala Seeds
Background & Aims of the Study: Heavy metals discharge to environment is a worldwide problem growing in scale. When they accumulate in the environment and in food chains, they can profoundly disrupt biological processes. Peganum Harmala Seeds (PHS) was used as a bio-sorbent, using a continuous system for removing Pb2+, Co2+, Ni2+ and Cu2+ ions from aqueous solutions. ...
