Simultaneous Determination of Hg(II), Cd(II), Pb(II) and Zn(II) by Anodic Stripping Voltammetry using Modified Carbon Paste Ionic Liquid Electrode
In the presented study, CuO-CoO-MnO/SiO2 nanocomposite was synthesis by Cu(II), Co(II), Mn(II), with 1:1:1 mole ratio and Tetraethyl orthosilicate. azo–azomethine 1-(3-imino-4-hydroxophenylazo-4-nitrobenzene)-4-methyl phenol (L) was synthesized and used as a ligand for capturing the metal ions. Also, 1-butyl-1-methylpyrrolidinium bis(trifluoromethylsulfonyl)imide was applied as the i...
متن کاملA Potentiometric Study of Guanidinoacetic Acid Complexation with the Ions Mn(II), Co(II), Ni(II), Cu(II), Zn(II), Cd(II) and Pb(II)
Foi estudado a complexação do ácido guanidoacético (AGA) com alguns íons de interesse biológico, a saber : Mn(II), Co(II), Ni(II), Cu(II), Zn(II), Cd(II) e Pb(II). Após o AGA ter sido sintetizado e caracterizado, foram determinadas potenciometricamente as constantes de dissociação deste ligante, assim como a de formação de seus complexos e hidroxicomplexos com os íons supracitados. A maioria do...
متن کاملRole of bound Zn(II) in the CadC Cd(II)/Pb(II)/Zn(II)-responsive repressor.
The Staphylococcus aureus plasmid pI258 cadCA operon encodes a P-type ATPase, CadA, that confers resistance to Cd(II)/Pb(II)/Zn(II). Expression is regulated by CadC, a homodimeric repressor that dissociates from the cad operator/promoter upon binding of Cd(II), Pb(II), or Zn(II). CadC is a member of the ArsR/SmtB family of metalloregulatory proteins. The crystal structure of CadC shows two type...
متن کاملAdsorption of Cu(II), Ni(II), Zn(II), Cd(II) and Pb(II) onto Kaolin/Zeolite Based- Geopolymers
This work deals with geopolymers based on local Jordanian resources, namely, kaolin and zeoltitic (phillipsite) tuff. The geopolymers were prepared from these two materials by a reaction with an alkali solution at 80oC. The research group of the present work has demonstrated in previous work that addition of zeolitic tuff to kaolin based-geopolymers increases the adsorption capacity toward Cu(I...
متن کاملRemoval of Pb(II) and Cu(II) Ions from Aqueous Solutions by Cadmium Sulfide Nanoparticles
In this study, cadmium sulfide nanoparticles (CdS NPs) were prepared, characterized and used as a new adsorbent for simultaneous removal of Pb(II) and Cu(II) ions from aqueous solutions. Using a batch adsorption method, the effects of solution pH, contact time, adsorbent dose, and temperature were studied and optimized. Removal efficiencies, higher than 98% were obtained for both the met...
