RECENT ACHIEVEMENT ON CARBON NANOTUBE-BASED ADSORBENT FOR ORGANOPHOSPHORUS PESTICIDES REMEDIATION– A MINI REVIEW

Abstract

Organophosphorus (OP) compounds are a broad category of chemicals that are used in both domestic and industrial applications. However, OPs are extremely toxic to various non-target species, humans included, with its most common side effects being acute cholinergic toxicity and delayed polyneuropathy. As these OP pesticides are difficult to hydrolyze, their extensive use has likely contributed to significant environmental pollution. To date, various pollutant adsorption techniques have been developed to overcome this pollution. Adsorption has been recognized as an effective technique both in detection and removal of OP pesticides since it is easy, cost-effective and environmentally friendly. Many studies have identified various effective adsorbents of OP such as graphene oxide (GO), silica particles, magnetic materials, nanocellulose and carbon nanotubes (CNT). Amongst these, CNT has been a research hotspot as an OP adsorbent in recent years due to its high specific surface area, high strength, excellent stability, controllable pore size and surface properties. Therefore, this manuscript provides a brief review of several recently published research on OP adsorption using CNT for removal and detection purposes.
