Natural polyphenols enhanced the Cu(II)/peroxymonosulfate (PMS) oxidation: The contribution of Cu(III) and HO•.

Water Research, 2020
Copper ion (Cu(II)) in water or wastewater has been reported to trigger peroxymonosulfate (PMS) oxidation of organic contaminants (OCs). However, this process can only work in alkaline condition, which limits its potential application.

Interfacial interactions between collected nylon microplastics and three divalent metal ions (Cu(II), Ni(II), Zn(II)) in aqueous solutions.

Journal of Hazardous Materials, 2020
In water environments, nylon microplastics (MPs) and heavy metals are two kinds of common pollutants. This study investigated the adsorption of three divalent metals (Cu(II), Ni(II), Zn(II)) onto collected nylon MPs as function of contact time ...

Interactions in Cu(II)Cu(II), VO(II)VO(II) and Cu(II)VO(II) pairs through oxalato bridging ligand

Inorganica Chimica Acta, 1984
Abstract The goal of this paper was to compare the interaction in Cu(II)Cu(II), VO(II)VO(II) and Cu(II)VO(II) pairs through the same oxalato bridging ligand. For this, two new bimetallic complexes were synthesized, namely acacVO(C 2 O 4 )VOacac·4H 2 O noted [VOVO] and tmenCu(C 2 O 4 )VO(C 2 O 4 )·3H 2 O noted [CuVO], with acac = acetylacetonato and ...

Adsorption behaviors of the pristine and aged thermoplastic polyurethane microplastics in Cu(II)-OTC coexisting system.

Journal of Hazardous Materials, 2020
In this work, the hypothesis that thermoplastic polyurethane (TPU) microplastics (MPs) could form complex toxic pollution by absorbing both antibiotics and heavy metals simultaneously was proposed.

Assembly of cyano-bridged Cu(II)/Cu(II) and Cu(I)/Cu(II) compounds obtained by controlled ration of cyanide

Journal of Organometallic Chemistry, 2007
Abstract One reaction system of Cu2+, dipn, and CN− with two different molar ratio sets of 1:1:5, and 2:1:8 produced two compounds 1 [CuII(dipn)][CuII(CN)4], and 2 [ Cu II ( dipn ) ] 2 [ Cu 4 I ( CN ) 8 ] · 2H 2 O , respectively (dipn = dipropylenetriamine).

Imidazolate bridged Cu(ii)–Cu(ii) and Cu(ii)–Zn(ii) complexes of a terpyridinophane azamacrocycle: a solution and solid state study

Dalton Transactions, 2007
The dinuclear Cu2+ and Zn2+ as well as the mixed Cu2+-Zn2+ complexes of a 5,5''-pentaazaterpyridinophane ligand (L) are able to incorporate imidazolate (Im-) as a bridging ligand. The crystal structure of [Cu(2)L(Im)(Br)(H2O)](CF(3)SO(3))(2).3H2O (1) shows one copper coordinated by the three pyridine nitrogens of the terpyridine unit, one nitrogen of ...

Overlooked Role of Coexistent Hydrogen Peroxide in Activated Peracetic Acid by Cu(II) for Enhanced Oxidation of Organic Contaminants.

Environmental Science and Technology
Cu(II)-catalyzed peracetic acid (PAA) processes have shown significant potential to remove contaminants in water treatment. Nevertheless, the role of coexistent H2O2 in the transformation from Cu(II) to Cu(I) remained contentious. Herein, with the Cu(II)/

Synthesis, structure and biomimetic properties of Cu(II)–Cu(II) and Cu(II)–Zn(II) binuclear complexes: possible models for the chemistry of Cu–Zn superoxide dismutase

Journal of Inorganic Biochemistry, 2005
Four imidazolate-bridged binuclear copper(II)-copper(II) and copper(II)-zinc(II) complexes viz., [(Bipy)(2)Cu-Im-Cu(Bipy)(2)](ClO(4))(3).CH(3)OH, [(Phen)(2)Cu-Im-Cu(Phen)(2)](BF(4))(3).2CH(3)OH, [(Bipy)(2)Cu-Im-Zn(Bipy)(2)](BF(4))(3), and [(Phen)(2)Cu-Im-Zn(Phen)(2)](BF(4))(3), (Bipy=2,2'-Bipyridyl, Phen=1-10-Phenanthroline and Im=imidazolate ion) were

Fabrication of magnetic bentonite/carboxymethyl chitosan/sodium alginate hydrogel beads for Cu (II) adsorption.

International Journal of Biological Macromolecules, 2019
In this work, composite hydrogel beads based on magnetic bentonite/carboxymethyl chitosan/sodium alginate (Mag-Ben/CCS/Alg) were fabricated and their ability to adsorb copper ions in water was studied.
