چکیده

Bis-(hydroxyamino)triazines (BHTs) constitute a new, general and highly versatile group of tridentate iron(III) chelating agents exhibiting higher affinity to iron(III) than other tridentate iron(III) chelators and superior iron(III) over iron(II) selectivity compared to desferrioxamine-B (DFO), EDTA as well as other tridentate ligands.

Complexation equilibrium between iron ( III ) and N , N ’ - bis ( 2 - hydroxyphenylmethyl ) - N , N ’ - bis ( 2 - pyridylmethyl ) - 1 , 2 - ethanediamine

Complexation equilibrium between iron(III) and N,N’-bis(2-hydroxyphenylmethyl)-N,N’-bis(2-pyridylmethyl)-1,2ethanediamine (H2bbpen), a colorless hydrophobic divalent hexadentate ligand, and potential use of the ligand for the spectrophotometric determination of iron(III) in aqueous solution was investigated. In the pH range 2.0 − 3.0, Fe(III) forms stable 1:1 complex with H2bbpen, and Fe(III) c...

Oxygen catalyzed mobilization of iron from ferritin by iron(III) chelate ligands.

Tridentate chelate ligands of 2,6-bis[hydroxy(methyl)amino]-1,3,5-triazine family rapidly release iron from human recombinant ferritin in the presence of oxygen. The reaction is inhibited by superoxide dismutase, catalase, mannitol and urea. Suggested reaction mechanism involves reduction of the ferritin iron core by superoxide anion, diffusion of iron(II) cations outside the ferritin shell, an...

Bis{2-[(2-benzoyl­hydrazin-1-yl­idene)meth­yl]-6-meth­oxy­phenolato}iron(III) chloride monohydrate

In the title mononuclear iron(III) complex, [Fe(C(15)H(13)N(2)O(3))(2)]Cl·H(2)O, the Fe(III) atom has a distorted octa-hedral geometry and is six-coordinated by four O atoms and two N atoms from two ligands. In the crystal structure, the complex cations, Cl(-) anions and water mol-ecules are connected into a chain along [100] through N-H⋯O, O-H⋯Cl and N-H⋯Cl hydrogen bonds. Two adjacent chains ...

Synthesis of magnetic iron oxide nanoparticles and its application for simultaneous determination of hydrazine and hydroxylamine

In the present paper, the electrochemical properties of magnetic iron oxide nanoparticles (Fe2O3 and Fe3O4) as highly sensitive sensors for the simultaneous determination of hydrazine and hydroxylamine was described. The electrochemical behavior of hydrazine and hydroxylamine was investigated using cyclic voltammetry, chronoamperometry and differentia...

Efficient masking of corrosion and fission products such as Ni(II) and Pd(II) in the presence of the minor actinide Am(III) using hydrophilic anionic or cationic bis-triazines.

Water soluble anionic and cationic bis-triazine ligands are able to suppress (mask) the extraction of corrosion and fission products such as Ni(II) and Pd(II) that are found in PUREX raffinates. Thus it is possible to separate these elements from the minor actinide Am(III). Although some masking agents have previously been developed that retard the extraction of Pd(II), this is the first time a...
