Valorization of keratin biofibers for removing heavy metals from aqueous solutions [PDF]
, 2018 Four common waste keratin biofibers (human hair, dog hair, chicken feathers, and degreased wool) have been used as biosorbents for the removal of heavy metal ions from aqueous solutions. Different parameters of the biosorption processes were optimized in

Copper(II) complexes with a flexible oxamato ligand [PDF]
, 2010 We report on a convenient synthesis of the ligand precursor, diethylethylene-1,2-bis(oxamate), (Et2H2oeo, 1), and show how a partial and preferential hydrolysis of the ester group can give rise to the dianionic ligand, (H2oeo)2−.

Cu(II) Ion-Selective Electrodes Based on Cu(II) Complex with Cyclized Salophen
Zeitschrift für Naturforschung B, 2003 Several versions of Cu(II) ion selective electrodes (ISE), based on cyclized N,N'-bis(salicylidene)-o-phenylenediamine (salophen) complexes with Cu(II), were fabricated for determination of Cu(II) in aqueous solutions. The response of the ISE was optimized by variation of membrane composition and evaluation of various experimental conditions.

Magnetic correlations on the full chains of Ortho-II YBa$_2$Cu$_3$O$_{6.5}$
, 2008 We propose that the NMR line shape on the chain Cu in the stoichiometric high-$T_c$ superconductor Ortho-II YBa$_2$Cu$_3$O$_{6.5}$ is determined by the magnetization induced on Cu near O vacancies, due to strong magnetic correlations in the chains.

Adsorption of Cu(II) Ions onto a Cellulosic Biosorbent, Leaf Powder: Application in Water Treatment
Adsorption Science & Technology, 2010 In the present work, Azadirachta indica (neem) leaves were converted to a powder for use in the separation of Cu(II) ions from water. The powdered biomass was investigated as a sorbent for Cu(II) ions employing pH, time, initial Cu(II) ion concentration ...
