Biosorption of heavy metals by bacterial biomass has been the subject significant research interest in last decades due to its efficiency, relatively low cost and minimal negative effects for surrounding environment. In this meta-analysis, biosorption efficiencies different strains Cu(II), Cd(II), Zn(II), Cr(III), Mn(II), Pb(II) Ni(II) were evaluated. Optimum conditions process such as initial ...

Abstract This article described a process for the preparation of Fe 3 O 4 nanocatalyst modified with Mn(II), Cu(II) and Zn(II) ions immobilised catalase. The effectiveness description ion sorption was compared four equilibrium models: Langmuir, Freundlich, Redlich–Peterson Sips. proposed models allow both single- multi-component sorption. results were also verified by DFT analysis. Langmuir mod...

A triangular framework with a terpyridine and shielded phenanthroline at its termini constitutes an open/close nanoswitch that is toggled by chemical inputs. In the presence of copper(I) ions, the open triangular framework (OPEN-I) firmly closes to a catalytically inactive heteroleptic [Cu(phen)(terpy)](+) complex (CLOSE). Reversible switching between CLOSE and OPEN-I states was demonstrated by...

Cross-linked metal-imprinted chitosan microparticles were prepared from chitosan, using four metals (Cu(II), Zn(II), Ni(II), and Pb(II)) as templates, and epichlorohydrin as the cross-linker. The microparticles were characterized by Fourier transform infrared spectroscopy, solid state (13)C nuclear magnetic resonance spectroscopy, and energy-dispersive X-ray spectroscopy. They were used for com...

The paper presents the use of Pyrolox™ containing manganese nano oxides used for the removal of Cu(II), Zn(II), Cd(II), and Pb(II) as well as U(VI) ions. Their concentrations were analyzed using the atomic absorption spectrometer SpectrAA 240 FS (Varian) as well as UV-vis method. For this purpose the static kinetic and equilibrium studies were carried out using the batch technique. The effect o...
