Abstract
A single flow channel analysis system that employs the formaldehyde-S(IV)-pararosaniline color reaction has been developed for the determination of aqueous S(IV). The system employs a passive cation-exchange membrane reactor for the introduction of base and a pressurized porous membrane reactor for the introduction of acidic pararosaniline. The detection limit is 1.6 x 10/sup -7/ M S(IV); the sample size is 200 ..mu..L, and the throughput rate is 15/h. Results for cloudwater samples are presented. 15 references, 3 figures, 1 table.
