title: Kinetics of adsorption of hydrocarbon chloro-derivatives from seven-component aqueous solution onto a thin layer of DTO-activated carbon.
abstract: The mass transfer and effective intraparticle diffusion coefficients were determined in the adsorption process of 1,2-dichloroethane, 1,1,2,2-tetrachloroethane, chloroform, carbon tetrachloride, 1,1-dichloroethene, perchloroethene, and 1,1,2-trichloroethene from seven-component aqueous solution onto a thin layer of activated carbon. A modified constant-volume method was used in the studies. A correlation between similarity numbers in the form of Sh=2+1.54Re(0.66)Sc(0.33) was derived for a range of the Reynolds numbers in(1-15). Based on the Biot number, it was found that within the range of Reynolds numbers <14 the mass transport through a film decides the adsorption rate.
