Abstract
Chemical pesticides are one of the most frequently encountered pollutants in multiple water sources and made their way into biomagnification. Short-term exposure to pesticides causes headache, vomiting, nausea, blurred vision, pupil constriction, muscle tremors, excessive sweating, etc. whereas prolonged exposure can lead to severe neurological problems, coma and even death. However, conventional methods have been proved to be inefficient in complete removal of pesticides. Over the past few years, nanotechnology is considered to play a significant role in influencing the current environmental engineering and science owing to their excellent physico-chemical properties and tuneable functionalities. Nanomaterials are massively enrolled as adsorbents and photocatalysts for the removal of various chemical pesticides from different sources. In present article, the applicability of different nanomaterials for the removal of various pesticides via adsorption and photocatalytic degradation from aqueous environment was discussed. Furthermore, the influence of surface treatment to their functionalities and efficiencies was reviewed and highlighted.
