The accurate detection of Cd2+ and Pb2+ in soils by square-wave anodic stripping voltammetry (SWASV) faces great challenges because the interaction between multiple heavy metal ions (HMIs) interferes seriously with their SWASV signals. To detect high accuracy, an overlooked but informative signal, i.e., current peak area, was employed combined chemometric methods to suppress above mutual interf...

The present study synthesizes a novel adsorbent by coating Fe3O4 magnetic nanoparticles with amino functionalized mesoporous silica. The FTIR spectrums indicate that silica has been successfully coated on the surface of Fe3O4 and 3-aminopropyl tri methoxysilane compound have been grafted to the surface of silica-coated Fe3O4. The XRD analysis shows the presence of magnetite phase with cubic spi...

The present study was carried out to investigate the adsorption and leaching behavior of Cu2+, Zn2+ and Pb2+ by sediments collected from the western banks of three different sectors along River Nile at Aswan governorate, Egypt. The feasibility of sediments for the removal of Cu2+, Zn2+ and Pb2+ from aqueous solutions was tested under the effect of three conditions (pH, initial metal concentrati...

The 2-TM-GxN family of membrane proteins is widespread in prokaryotes and plays an important role transport divalent cations. canonical signature motif, which also a selectivity filter, has composition Gly-Met-Asn. Some members though deviate from this composition, however no data are available as to whether any functional implications. Here we report the structural analysis CmaX protein pathog...

Leachates from mine tailing ponds, which usually contain a variety of metallic ions, are highly toxic to human and ecological health. The common methods used remove those trace difficult due the extremely acidic conditions diverse kinds metals in leachates. Herein, we proposed an economical efficient soil-assisted alkali suspension approach reclaim metals. Under optimum conditions, more than 98...

Sperm cell and embryo toxicity tests using the Mediterranean sea urchin Paracentrotus lividus Lmk were performed to assess the toxicity of As3+, Cd2+, Cr3+, Ni2+, Pb2+, Cu2+, Zn2+, and Hg2+. The aim of this study was to improve information about the comparative sensitivity of sea urchin bioassays to the heavy metals, which are an important cause of contamination in the ecosystem of the Lagoon o...

the performance of olive stone activated carbon (osac) for sorption of cu2+, zn2+ and ni2+ ions was investigated via batch technique. osac materials were prepared under different physially activation conditions. olive stone waste was physically activated with n2 gas and steam gas at 900oc at 3.5h hold time (osac-3) was choice as the best one for cu2+, zn2+ and ni2+ removal. characterization for...
