摘要：
A highly sensitive catalytic spectrophotometric method is proposed as a new method for the determination of Se(IV) and Se(VI). The method is based on the catalytic effect of Se(IV) in redox reaction of bromate with semicarbazide in hydrochloric acid media. The determination range of both analyses is 50-4000 ng . ml(-1). Selenium as low as 43 ng . ml(-1) could be determined by this method. The application of the method to the determination of selenium in Kjeldahl tablets and in a health-care product is described.
