Title

The Effect of Zero Valent Iron Nanoparticles on Reduction of Heavy Metal Contamination in Calcareous, Acidic and Sandy Soils

Pages

  799-809

Abstract

 Nowadays contamination of soils containing Heavy metals is among the great environmental concerns of the human beings. The application of zero valent iron nanoparticles (ZVINs) as an amendment for environmental pollutions has been highly considered by many researchers in last few decades. This study was conducted to synthesize and characterize the ZVINs stabilized with Carboxyl methyl cellulose (CMC-ZVINs) in aerobic conditions and to assess their ability for reduction of DTPA extractable lead (Pb), cadmium (Cd), nickel (Ni) and copper (Cu) from some three polluted soils including sandy-calcareous, acidic as well as clay-calcareous soils. An experiment of completely randomized design of a factorial arrangement of treatments consisting of nano zero valent iron doses (0, 0. 5, 1 and 2 w/w %), soils (sandy-calcareous, acidic and clay-calcareous soils) within two time periods (10 and 20 days) with three replications was carried out. The results of SEM and XRD analyses indicated that the CMC-ZVINs with the mean size of less than 50 nm and a maximum of 2θ peaks at 44. 8° confirmed the nano sized and zero valent status of particles, respectively. Results also indicated that the DTPA extractable Pb, Cd, Ni and Cu within the three polluted soils decreased with increase in zero valent iron nanoparticle dosages. The percentage of available Pb reduction was higher in comparison with other Heavy metals. The aging of nanoparticles from 10 to 20 days led to more significant reduction of DTPA extractable Heavy metals. Overall, the synthesized CMC-ZVINs can potentially be introduced as an effective remediation approach for Pb, Cd, Ni and Cu contaminated soils.
