A comparison of the kinetics of spreading of aqueous solutions of two different surfactants on an identical substrate and their short time adsorption kinetics at the water/air interface has shown that the surfactant which adsorbs slower provides a higher spreading rate.

Chitosan was crosslinked using epichlorohydrin as crosslinking agent to prepare crosslinked chitosan which was used as an adsorbent for the removal of Zn(II) from aqueous solutions. The adsorption prosperities of Zn(II) on crosslinked chitosan were studied, including the influence of pH value and the adsorption kinetics. The kinetics of adsorption was discussed using two kinetic models, the pseudo first-order and the pseudo second-order model. Results reveal that the crosslinked chitosan is suitable as adsorbent to remove Zn(II) from dilute solution. The rate parameters for the Zn(II) by crosslinked chitosan were also determined. It was shown that the adsorption kinetics of Zn(II) could be best described by the pseudo second-order model and the adsorption process may involve a physical adsorption.

Abstract Adsorptive removal of 2-, 3- and 4-chlorophenol from aqueous solutions by granular activated carbon was studied. The influence of different experimental parameters like initial concentration, carbon dosage and pH on the adsorption of monochlorophenols were evaluated. The influence of type of acid and base used for water acidification or alkalization was also tested. The results indicate that acidic pH is favorable for the adsorption of chlorophenols; however the type of acid or alkali used for the change of pH has a little influence and did not significantly affect the adsorption efficiency. The pH played an important role in the adsorption kinetics of chlorophenols at pH values above the pKa values of the compounds, while little influence on adsorption rate was observed if pH was decreased below the pKa values
