Monitoring the quality of water in the lakes of Kiev on the presence of lead, zinc, copper by employing the solid phase concentration on bifunctional modifed adsorbent
Contamination of water resources with heavy metals attracts a great interest of scientists nowadays. In this regard, our group has proposed an approach to characterize a group of heavy metals in drinking water sources: solid phase extraction on the modified silica sorbents. In order to quantify such metal ions as copper, zinc and lead we graft the EDTA groups on silica surface. EDTA is well-known ligand which forms strong complexes with the number of metals in solution. Immobilization of EDTA on the surface will allow to concentrate the metal on solid support and diminish its presence in the water. Furthermore this route allows to use the eluate solution to desorb the metals and quantify its amount by atomic absorption spectroscopy.
The proposed strategy was successfully employed to gather the metals from well, lake and rain water and characterize its content.
