Effects of thiocyanate on Ni(Hg)/Ni(II) and Ni/Ni(II) electrode reactions

Journal of Electroanalytical Chemistry and Interfacial Electrochemistry, 1974
Summary Chronopotentiometric and stationary polarization measurements have been performed on mercury, nickel, and platinum electrodes in aqueous solutions of x M NiCl2+y M KSCN+(1−2x−y) M KCl at 25°C. Reaction products have been studied by electrochemical, radio-tracer, electron-microprobe, and X-ray diffraction techniques.

A Dinuclear Ni(II) Complex with Two Types of Intramolecular Magnetic Couplings:  Ni(II)−Ni(II) and Ni(II)−TTF^•+

Inorganic Chemistry, 2006
A dinuclear Ni(II) complex involving tetrathiafulvalene (TTF) radicals as ligands has been prepared and characterized, [Ni2(mu-Cl)2(L*+)2(I3)4(I2)3.(H2O)2.(C4H8O)3 (1), L = 4,5-bis(2-pyridylmethylsulfanyl)-4',5'-ethylenedithiotetrathiafulvalene. There are two types of intramolecular magnetic exchange interactions, namely one ferromagnetic Ni(II)-Ni(II)

Cycle of Ni(II)-Ni(III)-Ni(II) in Ni-doped layered double hydroxides for activation of intercalated peroxydisulfate

Chemical Engineering Journal, 2020
Abstract Peroxydisulfate (PDS) activation has attracted much attention for the treatment of drinking water systems. In this work, Ni-doped MgAl layered double hydroxides (Ni-LDHs, Ni:Mg = 1:100 to 1:1, molar ratio) were prepared for the activation of PDS via intercalation.

Adsorption of Ni(II) on clays

Journal of Colloid and Interface Science, 2006
The present work investigates the adsorptive interactions of Ni(II) ions with kaolinite, montmorillonite, and their poly(oxo zirconium) and tetrabutylammonium derivatives in aqueous medium. Batch adsorption studies were carried out with various Ni(II) concentrations, amount of clay adsorbents, pH, agitation time and temperature.

Ni(iii) vs. Ni(ii)-thiyl radical: charge-delocalisation in a binuclear Ni(iii)Ni(ii)-dithiolate complex

Chemical Communications, 2003
Multi-frequency EPR spectroscopy on 61Ni-labelled samples of [Ni2(L)]3+ confirms extensive charge-delocalisation between the Ni(III) centre and thiolate donors in the Ni(II)Ni(III) complex.

Ni(II) and Zn(II) perthiocarboxylates

Journal of Inorganic and Nuclear Chemistry, 1971
Abstract The synthesis by Bruni and Levi, modified by Fackler and Coucouvanis, from aldehydes and ammonium polysulfide has been extended to aliphatic aldehydes, and perthiopivalate (CH 3 ) 3 CCSSS − has been prepared. This ligand forms 1:2 Zn(II) and Ni(II) complexes, analogous to the already known complex perthiobenzoates and perthio- p -toluates.

Ferromagnetic Ni^II Discs [PDF]

Chemistry – A European Journal, 2009
AbstractA family of planar disc‐like hexa‐, octa‐ and decametallic NiII complexes exhibit dominant ferromagnetic exchange. The deca‐ and octametallic clusters [NiII10(tmp)2(N3)8(acac)6(MeOH)6] (1, H3tmp=1,1,1‐tris(hydroxymethyl)propane; acac=acetylacetonate) and [NiII8(thme)2(O2CPh)4(Cl)6(MeCN)6(H2O)2] (2, H3thme=1,1,1‐tris(hydroxymethyl)ethane ...

The binding of Mg(II) and Ni(II) to synthetic polynucleotides

Biophysical Chemistry, 1987
Equilibria and kinetics of the interactions of Mg2+ and Ni2+ with poly(U), poly(C) and poly(I) have been investigated at 25 degrees C, an ionic strength of 0.1 M, and pH 7.0 or 6.0. Analogous studies involving poly(A) were reported earlier. All binding equilibria were studied by means of the (usually small) absorbance changes in the ultraviolet range ...

Complexation of Ni(II) by Dimethylglyoxime for Rapid Removal and Monitoring of Ni(II) in Water

Mine Water and the Environment, 2016
The complexation of Ni(II) with dimethylglyoxime (DMG) entrapped within a Nafion membrane and a DMG–sol–gel matrix was studied and compared for different solutions. First and pseudo-second order kinetic models, Elovich, intra-particle, and liquid film diffusion models were applied to evaluate sorption kinetics.

Thermal decomposition of hydrated salts of Ni(II)-acetate and Ni(II)-lactate

Journal of Molecular Structure, 2013
The formation and microstructure of thermal decomposition products obtained in air from Ni(II)-acetate tetrahydrate and Ni(II)-lactate tetrahydrate were investigated using XRD, Raman, UV/Vis/NIR and FE-SEM/EDS techniques. The formation of metallic Ni particles was due to the presence of acetate and lactate groups as reducens and with an increase in the
