| Abstract;A chemiluminescence (CL) method using flow injection (FI) was developed for the determination of uric acid based on the enhancement chemiluminescence intensity of luminol-hexacyanoferrate(III)-hexacyanoferrate(II) in the presence of cetyltrimethylammonium bromide and the uric acid species. The linear range was 7.0 * 10-10-9.0 * 10-7 M with a detection limit (3.SIGMA.) of 2.58 * 10-10 M, which was about two orders of magnitude lower than those reported. The proposed method was used for the determination of uric acid in real samples. (author abst.) |
