Dithiocarbamate ligands as heavy metal expectorants from aqueous solutions

چکیده
The uncontrolled concentrations of heavy metals introduced into the water sources need an effective method for their removal. dithiocarbamate (dtc) ligands are most popular precipitating agents used removal from wastewater. Presently, two novel dtc ligands, one without methylene linker (K2L1) and other with (K2L2) were eight ions including Fe2+, Co2+, Ni2+, Cu2+, Cd2+, Ag+, Zn2+ Pb2+ aqueous solution. These contain acyl (NH-C = O) S, S (thiolate) functional groups. results indicated that metal efficiency both was almost 100% at pH 4 7 free effect groups but depends on binding sites. It exhibited a distinct selectivity (Pb2+ ∼ Cu2+ Ag1+ > Cd2+ Co2+ Ni2+ Fe2+). developed methods have potential can be thiophilic water-soluble.HIGHLIGHTS Water treatment, contaminated by ions.Synthesis characterization ligands.Effect (-CH2-) dithiocarbamtes extraction.pH temperature extraction ligands.

متن کاملAgricultural waste material as potential adsorbent for sequestering heavy metal ions from aqueous solutions - a review.
Heavy metal remediation of aqueous streams is of special concern due to recalcitrant and persistency of heavy metals in environment. Conventional treatment technologies for the removal of these toxic heavy metals are not economical and further generate huge quantity of toxic chemical sludge. Biosorption is emerging as a potential alternative to the existing conventional technologies for the rem...
