Abstract: Pesticide pollution of the hydrological system is an issue of public health concern due to the ensuing ecological and human health predicament associated with pesticide contamination of drinking water and the aquatic ecological system. To this end, this paper provides insight into the role of adsorption, as an economic and environmentally friendly technique for the removal of pesticide residues from wastewater. Conventional materials such as wood sawdust and cork wastes have been respectively reported with 4.5 to 69.44 mg/g and 2.03 to 19.08 mg/g adsorptive capacities for the removal of dichlorodiphenyltrichloroethane, whereas higher adsorptive capacities ranging from 193 to 205 mg/g have been obtained for carbofuran removal using mesoporous activated carbon derived from coconut frond. Moreover, 14.9 to 92.2 mg/g adsorptive capacities have been reportedly obtained for glyphosate removal from water using zeolite. Comparatively, magnetic multi-walled carbon nanotubes@ organic framework has been reported with lower adsorptive capacities (2.18 to 3.39 mg/g), compared to fluffy ball-like covalent organic framework with higher adsorptive capacities (163.9 to 178.6 mg/g) for removing organophosphorus pesticide from water. Also, insight into the adsorption mechanism and regeneration of pesticide-spent adsorbents has been provided, with consideration of the challenges and future perspectives on the role of adsorption for the removal of pesticides from water/wastewater.
