Carbon nanotubes: An efficient sorbent for herbicide sensing and remediation

Abstract

Major environmental contaminants such as pesticides are extensively used in agronomic practices such as insecticides, fungicides, rodenticides, and herbicides, but the toxicological problems connected to their persistent residues were noticed Agri-Ecosystems. Some types of nanomaterials offer multiple probable benefits to upgrade existing environmental conditions through employing innovative resources with practical performance, generating less utilization of energy levels and materials. Carbon nanotubes were mainly focused on the dispersive solid phase extraction (SPE) approach utilizing, as a kind of sorbents in a loaded column that is used to the herbicides' extraction for different environmental samples. This chapter emphasizes the usage of this technology for extraction and detection, followed by degradation and finally the herbicide removal using carbon nanomaterials. We have summarized the recent advances in detecting and degradation herbicides such as Diuron, Fenuron, Dicamba, Metribuzin, Sulfentrazone, Atrazine, toxins, etc., by using electrochemical methods and optical methods such as single- or multiwalled carbon nanotubes. However, carbon nanomaterials represent competitive sorbent materials, which occur more advantageously in natural conditions.
