2.2- Dichloroethane desorption

Aochi, Y. O., and W. J. Farmer, Role of microstructural properties in the time-dependent sorption/desorption behavior of 1,2-dichloroethane on humic substances , Environ. Sci. Technol., 31,2520-2526 (1997). 

In order to understand further the behavior for the four harbinger compounds as to their adsorption and desorption pathways, and to test the validity of reversible sorption, a series of experiments were performed whereby the adsorption step was followed by successive desorption using distilled water. The same four compounds (1,4-dichlorobenzene, 1,2-dichloroethane, 1,1,2-trichlor-ethane, and 1,1,2,2-tetrachloroethane) and a Pleistocene clay were used for the...

The adsorption of binary organic mixtures by a porous carbon was studied by Takeuchi and Furaya, the components being chosen such that some were accepted by and some excluded from 0.5 nm micropores. The experimental results could be represented by a combination of Freundlich adsorption isotherms, the parameters of which could be related to the physical properties of the adsorptives, and it was found possible to predict satisfactorily the adsorption isotherms of new systems. The adsorption by and desorption from active carbon has been reported by Andreikova, Kondratov, and Kogan, who found that adsorption from (unspecified) organic solvents decreased in the series phenol > quinoline > phenanthrene > acenaphthene > naphthalene. In desorption, acidic compounds are best desorbed with a mixture of methanol and dichloroethane but for basic compounds benzene is most effective.
