Commentary:Cross-linked poly(N-benzyl-4-vinylpyridinium bromide) (BVP resin in the bromide form) has an excellent capacity for removing sodium dodecylbenzenesulfonate (DBS) from aqueous solution. The breakthrough capacity of the resin with less than 1 ppm leakage in the effluent was greater than that observed with commercial anion exchange resins and porous styrene-divinylbenzene resin with no ion exchange functional groups. This capacity was scarcely affected by the presence of sodium chloride, sodium sulfate, sodium hydroxide, and hydrochloric acid. Adsorbed DBS was eluted from the BVP resin by a simple treatment with methanolic hydrochloric acid, and the BVP resin was efficiently regenerated as the chloride form. DBS was concentrated into 20-25 wt % solution. BVP resin in the chloride form showed much the same ability for the adsorption of DBS as BVP resin in the bromide form.
