【Abstract】 A chemiluminescence(CL) flow system is described for the determination of promethazine hydrochloride based on its direct oxidation with cerium(IV) in acidic media accompanied with chemiluminescence. The system responds linearly to promethazine hydrochloride concentration in the range 1 0×10 -7 ～1.5×10 -5 g/mL with a detection limit (3σ) of 4 0×10 -8 g/mL. Relative standard deviation (RSD) is 2 6% for 5 0×10 -6 g/mL promethazine hydrochloride ( n =11). The system has been successfully applied to the determination of promethazine hydrochloride in tablets.更多还原
