Preparation of Poly-porous Poly(NVP-co-NMBA) Sorbent and Octanol Solution of Adsorption of Dibenzothiophene in Dilute
多孔聚合物载体的制备及吸附脱除二苯并噻吩的初步探索

A porous polymeric sorbent was prepared with sucrose as pore-forming additive, and the sorbent beads are superior to non-porous polymeric sorbent in adsorption of DBT from a model gasoline. Adsorption of 16 mg/g DBT was achieved under the condition of 50 g/L of the polymeric beads at initial DBT concentration of 1.26 g/L. The sorbent beads are easily desorbed with toluene and can be reused with stabilized adsorption capacity.
