Preparation of polyethyleneimine/graphene oxide membranes and their adsorptions for Pb(II), Cu(II) and Zn(II) in mixed systems

open access: yesDesalination and Water Treatment
A series of novel polyethyleneimine/graphene oxide (PEI@GO) membranes were prepared and their adsorptions for heavy metal ions in mixed solutions were examined. It was found that they had good sorption performances for Pb(II), Cu(II), and Zn(II) in water.

Structural Snapshots of a Flexible Cu_2P_2 Core that Accommodates the Oxidation States Cu^ICu^I, Cu^(1.5)Cu^(1.5), and Cu^(II)Cu^(II) [PDF]

open access: yes, 2005
The phosphido-bridged dicopper(I) complex {(PPP)Cu}_2 has been synthesized and structurally characterized ([PPP]^- = bis(2-di-iso-propylphosphinophenyl)phosphide). Cyclic voltammetry of {(PPP)Cu}_2 in THF shows fully reversible oxidations at −1.02 V (Cu^(

INVESTIGATIONS ON THE FEASIBILITY OF ROMANIAN PINE BARK WASTES CONVERSION INTO A VALUE-ADDED SORBENT FOR CU(II) AND ZN(II) IONS [PDF]

open access: yesBioResources, 2011
The batch sorption capability of Romanian pine bark for the removal of Cu(II) and Zn(II) ions from diluted aqueous solutions was investigated as a function of initial pH, contact time, and temperature. The metal sorption sequence is Cu > Zn.

SOD activity of immobilized enzyme mimicking complexes [PDF]

open access: yes, 2003
A binuclear, imidazolato-bridged, possible superoxide dismutase-mimicking complex (Cu(II)-diethylenetriamino-μ-imidazolato-Zn(II)-tris-aminoethylamine-triperchlorate) was prepared and immobilized on silica gel or among the layers of montmorillonite.

Adsorbția Cu II cu ajutorul cărbunilor activi

open access: yes, 2022
Adsorption is a very effective process for a variety of applications, and now it is considered an economical and efficient method for metal ions removal from wastewaters. The most generally used solid adsorbent is the activated carbon, which is used as a very efficient solid adsorbent in many different applications. Activated carbons were prepared from
