Adsorption of Cd(II) and Pb(II) onto a one step-synthesized polyampholyte: Kinetics and equilibrium studies
(Elsevier Science, 2012-05)
A one step-synthesized polyampholyte, bearing carboxylate and 2-methylimidazole (2MI) groups, was tested as adsorbent for the removal of Pb(II) and Cd(II) from aqueous solutions. This material combines the benefits of ...
Adsorption of Cu(II), Zn(II), Cd(II), Hg(II) and Pb(II) from aqueous solutions on a 2-mercaptobenzimidazole-modified silica gel
(1990-01-01)
The chemically modified silica, obtained by reacting 2-mercaptobenz-imidazole with 3-chloropropyl silica gel, was used to adsorb Cu(II), Zn(II), Cd(II) and Pb(II) from aqueous solutions at various pH. Between pH 3-5, the ...

Evaluación de la contaminación por plomo derivada de la minería de carbón en Lenguazaque, Cundinamarca
(Universidad de los AndesGeocienciasFacultad de CienciasDepartamento de Geociencias, 2021)
Los isotopos de plomo son utilizados para definir las fuentes de contaminación en el ambiente. Se analizaron las concentraciones de Pb y los ratios 206Pb/207Pb, 206Pb/204Pb, 207Pb/204Pb y 208Pb/206Pb en muestras de los ...

Montmorillonite Facilitated Pb(II) biomineralization by Chlorella sorokiniana FK in soil
(Elsevier Science, 2021-11)
In this study, Chlorella sorokiniana FK, isolated from lead-zinc tailings, was employed for Pb(II) biomineralization with or without montmorillonite (MMT) addition in soil. Batch experiment results showed that montmorillonite ...
EXTRACTION OF FE(III), CU(II), CO(II), NI(II) AND PB(II) WITH THENOYLTRIFLUOROACETONE USING THE TERNARY SOLVENT SYSTEM WATER ETHANOL METHYLISOBUTYLKETONE
