TL;DR: In this paper, the effect of KCl on the adsorption of phenol, toluene, and benzene on activated carbon, with different degrees of surface oxygenation, was investigated Different trends of salt effect were observed for each compound.
Abstract: The effect of KCl on the adsorption of phenol, toluene, and benzene on activated carbon, with different degrees of surface oxygenation, was investigated Different trends of salt effect were observed for each compound The observed KCl effects were interpreted on the basis of electrical charge neutralization on the carbon surface and the adsorbate molecules, water adsorption, and the “salt out” effect In particular, water adsorption was found to be crucial in reducing the adsorption capacity of the activated carbon The influence of water adsorption was more pronounced on carbon surfaces with higher amounts of oxygen-containing groups This was additionally confirmed by measurements using flow microcalorimetry

TL;DR: The results show that even the addition of very low amounts of regenerated activated carbon resulted in the rapid adsorption of phenol in the Chemical solidification/stabilization (S/S) matrix, with phenol leaching reduced by as much as 600%.

TL;DR: It is postulated that for BSA adsorption on the Sepharose derivative of interest, attractive force interactions between adsorbed protein molecules drive the adsorptive process under overloaded conditions in a high (NH4)2SO4 environment.

TL;DR: The use of regenerated activated carbon as an immobilizing additive for phenol in solidification/stabilization (S/S) processes was investigated and the adsorption capacity was compared to that of the virgin form and was found to be very close.
