The Adsorption of 2,4-Dichlorophenoxyacetic Acid on a Mesoporous Material Based on Carbon Black

The kinetics of adsorption of 2,4-dichlorophenoxyacetic acid (2,4-D) from an aqueous medium on two microspherical nanoporous carbon materials with different times of activation in a medium of a water vapor is studied. The effect of the redistribution of the porous structure formed during the activation on the process of adsorption is studied. The pseudo-order of adsorption is determined as well, and a comparison of the parameters of the adsorption characteristics with the earlier studied microporous and mesoporous samples is performed.
