The hydroxy (RB 19-OH) and vinyl sulfone (RB 19-VS) derivatives of Reactive Blue 19 were identified in a textile wastewater using a gradient HPLC with a novel type of electrochemical detection. RB 19-OH could not be detected in the effluent of the wastewater treatment facility receiving the textile wastewater. RB 19-VS was present, however, in significant amounts. In laboratory studies, the hydrolysis kinetics of RB 19-VS were studied in phosphate buffer over a pH range of 4 to 11 and a temperature range of 25 to 85C. The half-life for RB 19-VS at pH=7 at 25C was calculated to be 46 years. Similarly, no loss of RB 19-VS could be detected in a natural water over a 3-week period. The half-life for the degradation of RB 19-VS in an anaerobic sediment-water system, however, was 2.5 days.
