Heavy metals create serious health problems, so the practical implementation and development of low-cost sorbent materials to remove heavy from ecosystem is a worldwide issue. The purpose this study find ligand that has potential adsorb aqueous soil samples also biological potential. For this, Schiff base, dimeric o -toluidine (SBL), been synthesized through condensation, characterized by spect...

Alloying or doping Pd may be an option for overcoming sulfur poisoning. The current investigation probes the mechanism associated with sulfur binding to determine if Nb and Cu are appropriate doping metals. In this study, the effect of doping Pd with Cu or Nb on the binding strength of H(2) and H(2)S was investigated using plane-wave density functional theory-based electronic structure calculat...

The present study comprises the synthesis of a novel composite polyaniline-wheat husk (PANI-WH) and adsorption heavy metals (Cu, Pb, Ni) by using this composite. Characterizations such as SEM were used to check chemical composition, state (XPS), crystallographic nature (XRD), functional groups (FT-IR) before after metals. results indicate that performance PANI-WH (on metals) is good with excell...

The interaction between some heavy metal ions such as of Pb(II), Cd(II) and Cu(II) ions from aqueous solution adsorbed by single walled carbon nanotube (SWCNTs) and carboxylate group functionalized single walled carbon nanotube (SWCNT-COOH) surfaces were studied by atomic absorption spectroscopy. The effect of contact time, pH, initial concentration of ion, ionic strength and temperature on the...

Biochars have been proposed for remediation of metal-contaminated water due to their low cost, high surface area and high sorption capacity for metals. However, there is a lack of understanding over how feedstock material and pyrolysis conditions contribute to the metal sorption capacity of biochar. We produced biochars from 10 different organic materials by pyrolysing at 450 °C and a further 1...

In this work, the removal of copper from an aqueous solution by granular activated carbon (GAC) in the presence of competitor ions was studied. A batch adsorption was carried out and different parameters such as pH, contact time, initial copper concentration and competitor ions concentration were changed to determine the optimum conditions for adsorption. The optimum pH required for maximum ads...

Department of Applied Sciences & Humanities, Moradabad Institute of Technology, Ram Ganga Vihar Phase – 2, Moradabad-244001 Abstract The removal of two heavy metals Cu and Zn from their aqueous solution, using steel industry slag as an adsorbent was studied as slag consist of calcium oxide, aluminum oxide, magnesium oxide etc. The research is a bench scale experimental type and analysis have pe...

background: the rapid increase in agricultural and industrial development has made heavy metal pollution a serious environmental problem and public health threat; therefore, removal of heavy metals from water is important. the current study prepared dnph@sds@fe3o4 nanoparticles as a novel and effective adsorbent for removal of hg(ii) ions from an aqueous solution. methods: a selective adsorbent...
