title: [Study on adsorption of methylene blue by sulfonated polyethersulfone I. The preparation of sulfonated polyethersulfone and its adsorption of methylene blue in water].
abstract: The evaluation of the adsorption of methylene blue (MB) in water by the sulfonated polyethersulfone (SPES) adsorbent column was carried out in this study after the SPES was prepared by gassy SO3 method. The polyethersulfone (PES) adsorbent column was used as control. The results indicated that the adsorption of MB by adsorbent column of SPES was more efficient than that of PES. In addition, the effect of the flow rate or ionic intensity on the adsorption and desorption of MB in water by SPES adsorbent column were also investigated. The results showed that the removal rate in water by SPES adsorbent column was larger than that in saline. However, the desorption experiment revealed that the desorption amount of the SPES adsorbent column in saline was larger than that in water.
