Active carbon from cedar nut shell for adsorption of 2,4-dichlorophenoxyacetic acid from an aqueous medium

Adsorption of herbicide, 2,4-dichlorophenoxyacetic acid (2,4-D), on active carbon samples based on cedar nut shell (CN) was studied. The textural characteristics of CN, adsorption capacity, and kinetics of 2,4-D adsorption from an aqueous medium were studied. The activation of CN in a water vapor was shown to result in the formation of a developed microporous structure providing a high adsorption capacity of the carbon with respect to 2,4-D.
