Potential application of nanomaterials in the treatment of contaminated sediment

Abstract

In the conducted research nano zero valent iron has been used as the immobilization agent in the remediation treatment of dredged sediment, as well as the treatment that is performed on-site (in-situ). Study aims to find a better understanding of the behavior of metals in sediments and to determine their potential mobility, bioavailability and potential toxicity based on sequential extraction procedures. In order to evaluate the extraction potential of toxic metals and the effectiveness of the treatment applied, three single-step leaching tests were performed. When applying nanomaterial, as the immobilization agent in sediment treatment, using two remediation options (ex - situ and in - situ), high stability of the metals is achieved in treated sediment.
