The complexes of Keggin and Dawson Structuresof transition metals substituted hetropolytungestate Cs5[PW11O39M-OH2].xH2O and K8[P2W17O61M-OH2].yH2Owhere M isMn2+, Co2+, Ni2=, and Zn2+) whith adnosinehave been synthsized ...
THEORETICAL STUDY ON THE MOLECULAR TAUTOMERISM OF THE 5-HYDROXY-2-HYDROXY METHYL PYRIDINE-4(1H)-ONE
5-hydroxy-2-hydroxy methyl pyridine- 4(1H)-one is one of the Hydroxypyridin-4(1H)-one
derivatives which are known in coordination as efficient metal ions chelators. In this work, relative
stabilities of 5-hydroxy-2-hydroxy methyl...
A new technique for extraction of metal ions in water samples, combination of multiwalled carbon nanotubes and polypropylene hollow fiber as a solid-liquid microextraction technique
A novel, simple, cost-effective, and sensitive method was developed for the determination of metal ions in water samples using multi-walled carbon Nanotubes as solid-phase adsorbents coupled with hollow fiber liquid phase microextraction...
THEORETICAL STUDY ON THE ABILITY OF THE (GLY)4 CYCLIC NANOPEPTIDE AS A SENSOR FOR ALKALINE EARTH METAL IONS
The cyclic peptides constructed of four sequences of glycine (CP) has been employed for selective complexation with Be2+, Mg2+, Ca2+, Sr2+ and Ba2+ metal ions. Obtained data, from the density
functional theory, showed that CP has the most...
Synthesis, Characterization and Adsorption of Metal Ions on New Silica-Gel Organofunctionalized Compound
Silica gel chemically modified with organic groups is
widely used as an adsorbent for metal ions. In this investigation,
silica gel was chemically modified with 3-chloropropyltrimethoxysilane
and reacted with 2-aminothiophenol...
Removal of transition metal ions from aqueous solution using dialdehyde phenylhydrazine starch as adsorbent.
DFT Study on the Selective Complexation of B12N12 Nanocage with Alkali Metal Ions
Density functional theory (DFT) calculations were applied at the M05-2X/6-311++G(d,p) level of the theory to investigate the interaction of the B12N12 nanocage (BN) and alkali metal ions (Li+, Na+, K+, Rb+ and Cs+) in the gas phase and in water...
Simultaneous Detection and Determination of Mercury (II) and Lead (II) Ions through the Achievement of Novel Functional Nucleic Acid-based Biosensors
The serious threats of mercury (Hg2+) and lead (Pb2+) ions for the public health makes it important to achieve the detection methods of the ions with high affinity and specificity. Metal ions usually coexist in some environment and foodstuff...
The effect of magnetic field on the stability of (18-crown-6) complexes with potassium ion
Macrocyclic polyethers are ligands with selectivity for metal ions. In order to understand the interactions between ligand, ion and solvent
we resorting to study of magnetic field effect on ion-macrocyclic complexes. Therefore, we studied...
