Abstract Aromatic hydrocarbons such as 2,4-dichlorophenoxyacetic acid (2,4-D), a common herbicide, is often found in groundwater in areas with intensive agricultural activities. Even in minute concentration, they are known to affect human health. An attempt has been made to capture 2,4-D from aqueous medium using neemoil-phenolic resin treated lignocellulosic jute. Treated jute showed 84% 2, 4-D removal efficiency. The 2,4-D removal of the biosorbent was confirmed from FTIR and 13C NMR analyses. The adsorption process was found to be spontaneous and effective over a pH range between 2 and 8. Maximum 2,4-D removal capacity of treated jute was found to be 38.5 mg/g. Treated jute was found to remove 2,4-D from aqueous media economically and efficiently through polar–polar and non-polar–non polar interactions. No sludge was produced during 2,4-D removal with treated jute nor did the process introduce deleterious characteristics, e.g., hardness and odor to the treated water.
