Accelerated degradation of bisphenol A induced by the interaction of EGCG and Cu(II) in Cu(II)/EGCG/peroxymonosulfate process

, 2020
Transition metals to activate peroxymonosulfate (PMS) has promising prospect to remove emerging organic contaminants, among which copper is an alternative because of its relatively high regulated concentration in drinking water and wide use of organic ...

Synthesis and Crystal Structure of Dissymmetrical Double Schiff Base Cu(II) Homobinuclear and Cu(II)‐Mg(II)‐Cu(II) Heterotrinuclear Complexes

Chinese Journal of Chemistry, 2006
AbstractHomobinuclear complex (HCuL)2 (1) (H3L: N‐3‐carboxylsalicylidene‐N′‐salicylaldehyde‐1,2‐diaminoethane) was obtained from self‐organization of the reported complex HCuL, and its crystal structure was determined through X‐ray diffraction at room temperature. The crystal of complex 1 belongs to monolinic system, the space group Cc, a=2.5326(5) nm,

Thermal Splitting of Bis-Cu(II) Octaphyrin(1.1.1.1.1.1.1.1) into Two Cu(II) Porphyrins

Journal of the American Chemical Society, 2004
When heated, bis-Cu(II) octaphyrin(1.1.1.1.1.1.1.1) is quantitatively split into two Cu(II) porphyrins both in solution and film states, which is accompanied by large absorption spectral changes.

Catalytic determination of Pb(II) in the presence of Cu(II)

Analytical and Bioanalytical Chemistry, 2002
A kinetic method is presented to determine micro-molar amounts of Pb(II) from various river and wastewater samples, in the presence of trace copper. The procedure is based on the catalytic effect of both species on the oxidation of mercaptosuccinic acid by chromate in acidic media. The extent of the reaction is followed spectrophotometrically at 420 nm

Coordination of Cu(II) in Cu(NO3)2 aqueous solutions

The Journal of Chemical Physics, 1984
Two concentrated copper (II) nitrate solutions have been examined by x-ray diffraction. The inspection of the radial distribution curves and the direct fitting of the structure functions suggested that a distorted arrangement of six oxygen atoms exists around the Cu2+ ion, probably in a tetragonally distorted, elongated octahedron.

Identification of Cu(II)/Cu(III) couples in binuclear copper(II) complexes

Polyhedron, 1985
Abstract A new series of binuclear copper(II) complexes were synthesised and studied by magnetic, spectral, ESR and cyclic voltammetry methods. The μeff values per copper atom correspond to the values observed for mononuclear copper(II) complexes.

Enhanced peroxymonosulfate activation for phenol degradation over MnO2 at pH 3.5-9.0 via Cu(II) substitution.

Journal of Hazardous Materials, 2018
Cu(II) doped mesoporous MnO2 (Cu-MnO2) was prepared to establish an intimate functional link between the structure substitution and catalytic peroxymonosulfate (PMS) activation.

Characterization of a Cu(II) complex of sulfadimethoxine

Journal of Inorganic Biochemistry, 2003
The molecular structure of [Cu(sulfadimet)(2)].SO(CH(3))(2) (sulfadimet=sulfadimethoxine=4-p-aminobenzenesulfonamido-2,6-dimethoxypyrimidine) was determined by single crystal X-ray diffractometry. It crystallizes in the monoclinic space group P2(1)/c with Z=4.
