A macroporous poly(styrene-co-divinylbenzene) resin having redox N,N-dichlorosulfonamide group, was modified for use in small-scale chlorination of potable water. The resin was synthesized via sulfonyl chloride by modification of the strong acid cation exchange resin, Amberlyst-15. The products obtained after treatment contained -SO2NH2 and -SO 3H groups. The sulfonic acid groups were determined by a total ion exchange capacity measurement. The sulfonamide groups were chlorinated mainly to the dichlorosulfonamide groups by laundry bleach acidified with acetic acid. The concentration of sulfonamide groups was determined by its chlorine holding capacity. The resin was further characterized by photoacoustic infrared spectroscopy. Tap water, sparged with air to remove chlorine, was passed through a column containing chlorinated resin at a flow rate of 5.0mL/min. Effluent water from the flow system was analyzed for free and combined active Cl. The resin was extracted with dichloromethane and examined for total organic carbon and by GC/MS and HPLC.
