Progress of Applications of Nanomaterials in Soil Heavy Metal Remediation |
| |
| Abstract: | Soil heavy metal contamination is one of the key environmental problems around the world and the application of nanomaterials in soil heavy metal remediation has gained increasing attention in recent years. In this paper, nanomaterial/modified nanomaterial application, application of nanotechnology combined with other soil remediation technologies and main factors affecting the nanomaterials application in soil heavy metal remediation are summarized. It is suggested that new nanomaterials should be developed which feature the enhanced diffusion in soil, and fast transformation from laboratory experiments to field applications. In addition, environmental behavior of the nanomaterials and their remediation mechanism should be explored. This paper will help to fully understand and further promote the application of nanomaterials in soil heavy metal remediation. |
