Study of the treated and magnetically modified bentonite as possible sorbents of heavy metals
Bentonite with its unique structural properties is a valuable material for environmental application. Its sorption properties are usually improved by the different ways of modification. In this work, the special sedimentation method was used for the treatment of the natural bentonite to obtain monomineral fraction of montmorillonite. The modification by iron oxide particles was used with the ai...
متن کاملGrowth and Heavy Metals Uptake of Puccinellia distans (Jacq.) Parl
The use of plants to remediate contaminated soil has been the most rapidly developing component in environmental cleansing. Although total concentration of heavy metals in soil is used for regulatory review, it also is beneficial to assess the potential for ecosystem impact through a series of bioassays. One commonly used bioassay is seed germination. In current research study effect of contami...

Cysteine-functionalized chitosan magnetic nano-based particles were synthesized for the sorption of light and heavy rare earth (RE) metal ions (La(III), Nd(III) and Yb(III)). The structural, surface, and magnetic properties of nano-sized sorbent were investigated by elemental analysis, FTIR, XRD, TEM and VSM (vibrating sample magnetometry). Experimental data show that the pseudo second-order ra...
متن کاملPhenanthrene Sorption onto Kaolinite; Heavy Metals and Organic Matter Effects
Several factors effect on sorption of polycyclic aromatic hydrocarbons (PAHs) in soil. Coexistence of metals and organic matter of soil are among important affecting factors on sorptive behavior of PAHs. This research investigated the effect of organic matter content and heavy metals (lead, nickel and zinc), on sorption of phenanthrene onto kaolinite. For this purpose, sorption of the organic m...
