Tuning the Surface Functionality of Fe(3)O(4) for Sensitive and Selective Detection of Heavy Metal Ions

The functionalization of materials for ultrasensitive detection of heavy metal ions (HMIs) in the environment is crucial. Herewith, we have functionalized inexpensive and environmentally friendly Fe(3)O(4) nanoparticles with D-valine (Fe(3)O(4)–D–Val) by a simple co-precipitation synthetic approach...

description The functionalization of materials for ultrasensitive detection of heavy metal ions (HMIs) in the environment is crucial. Herewith, we have functionalized inexpensive and environmentally friendly Fe(3)O(4) nanoparticles with D-valine (Fe(3)O(4)–D–Val) by a simple co-precipitation synthetic approach characterized by XRD, FE-SEM, and FTIR spectroscopy. The Fe(3)O(4)–D–Val sensor was used for the ultrasensitive detection of Cd(+2), Pb(+2), and Cu(+2) in water samples. This sensor shows a very low detection limit of 11.29, 4.59, and 20.07 nM for Cd(+2), Pb(+2), and Cu(+2), respectively. The detection limits are much lower than the values suggested by the world health Organization. The real water samples were also analyzed using the developed sensor.
