Abstract

At pH 7.0, batch adsorption methods were employed to reveal the adsorption/desorption behaviors of phthalic acid (PA) and benzoic acid (BA) on three functionalized carbon nanotubes (H-CNTs, C-CNTs and G-CNTs), and further to explore the impact of co-existing BA on PA adsorption by CNTs. The results showed both of Langmuir and Freundlich models could well fit with all experimental data, and Freundlich model was better (Adj r² > 0.88). The adsorption affinities of PA and BA on three CNTs were in order C-CNTs > H-CNTs > G-CNTs. In this study, obvious adsorption/desorption hysteresis was observed for both PA and BA on C-CNTs and H-CNTs, but not for G-CNTs. It was indicated that the adsorption of BA and PA on C-CNTs and H-CNTs had a relatively intensified chemical interaction, but due to lacking of surface oxygen functional group, desorption hysteresis was not observed on G-CNTs. For the co-existing system, PA was selected as main adsorbate and BA was selected as competitive adsobate to investigate competitive adsorption between two different ionizable compounds. The results indicated that on H-CNTs and C-CNTs, coexisting BA played a competitive role in PA, while on G-CNTs, coexisting BA had a synergistic adsorption effect on PA.

Key words： benzoic acid phthalic acid carbon nanotubes adsorption and desorption synergistic adsorption
