摘 要：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 6.2×10-5 mol·L-1（S/N=3）. It was applicable to the determination of penicillamine in the concentration range of 2×10-6～5×10-4 mol·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）.
