Summary:In this study, the polysulfone (PSF) capsules containing graphite nanosheets (GNS) were successfully prepared by a phase inversion precipitation method. Scanning electron microscopy and thermogravimetry were employed in the characterization of the as‐prepared PSF/GNS composites capsules. Meanwhile, the adsorption properties of the composites capsules for the phenol in aqueous solution were investigated by batch methods. The results showed that the phenol adsorption uptake would be increased with the enhancement of initial concentration and adsorption time, and the adsorption of phenol should be more favorable at pH value less than 9. The composites capsules would be a kind of promising alternative adsorbent with high adsorption capacity for the phenol from aqueous solutions at a low concentration. The adsorption kinetics of the capsules for phenol accorded with pseudo‐second‐order model, and the best fits of adsorption isotherms followed the Freundlich equation. POLYM.
