Abstract: A new flow-injection procedure has been developed for the determination of penicillamine based on the enhancement of the chemiluminescence (CL) reaction of the penicillamine-cerium (Ⅳ)-hydrocortisone system. The method was simple, selective and sensitive with a detection limit of 6.2×10-5mol·L-1 (S/N=3). It was applicable to the determination of penicillamine in the concentration range of 2×10-6~5×10-4mol·L-1. The method was successfully applied to the determination of penicillamine in tablets. The relative standard deviation (RSD) was 1.42% (n=7) and the recovery was 97%~103% (n=4).
