Isolation and Structural Characterization of Alkali and Alkaline Earth Metal Salts with Synthetic Non Cyclic Ionophores
In the present study, an investigation on the complex formation between mono- and divalent metal ions (Na+, K+, Li+ and Mg2+) in the form of salt with different podands using various solvents has been carried out. Isolated complexes were characterized by different spectroscopic techniques viz. IR, NMR and elemental analysis. On the basis of ...
متن کاملNew "off-on" responsible fluoroionophores for alkaline earth metal ions based on benzo-15-crown-5 bearing 9-phenanthreneacetamide.
The photochemical behaviors of a series of 9-phenanthreneacetamide (PA) derivatives were investigated using UV, fluorescence, and (1)H-NMR spectroscopy in acetonitrile solutions. To apply the electron transfer (ET) action of PA as a detecting moiety of chemosensors, 4'-(9-phenanthreneacetamido)-benzo-15-crown-5 (1) and 3'-methyl-4'-(9-phenanthreneacetamido)-benzo-15-crown-5 (2) were synthesized...

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 کاملPVC-Based Cerium Phosphate Membrane Exhibiting Selectivity for Molybdate Anions
A PVC-based membrane containing cerium phosphate was developed. Unlike the cerium phosphate itself that acts as a cation exchanger, the membrane exhibited anion-exchange properties. Therefore, the utility of this compound as a sensory element for detection of molybdate ions was pursued. The response of molybdate selective electrode based on this membrane was perfectly linear in the concentr...
