Synthesis of dithiocarbamate coated nanomagnets and their application in removal of heavy metal ions Print

Heavy metal ions، especially mercury، lead، and copper are found in the waste water used in the chemical industry، particularly in the nuclear industry، dye and metallurgy. These pollutants affect the health of humans and other organisms، so the removal of the pollutants from the wastewater is very important. In this paper dithiocarbamate coated iron oxide nanoparticles (DTC-MNP) were synthesis and were used for the separation of heavy metal ions from contaminated water. The adsorption performances of DTC-MNP towards heavy metals such as Cu (II) and Hg (II) were systematically investigated based upon which the adsorption mechanisms were deeply exploited. The adsorption of Cu (II) and Hg (II) onto DTC-MNP was strongly dependent on pH of the system. The results showed that the dithiocarbamate coated nanomagnets can remove heavy metals such as copper and mercury particles up to 200 ppm.
