Study of 2,4-dichlorophenoxyacetic acid (2,4-D) removal by Cu-Fe-layered double hydroxide from aqueous solution

- The Cu-Fe-NO3-LDH was used as sorbent for the 2,4-D from aqueous solution.
- The pH of the solution has a significant effect on the uptake of 2,4-D.
- The adsorption process was followed pseudo-second-order kinetic model.
- The nature of adsorption was spontaneous, exothermic and a physisorption.
