| 摘 要： | Introduction Rifampicin, a semi synthetic compound, is used primarily in the treatment of tuberculosis, and it is also an excellent amistaphyloco antibiotic when used in combination with other antibiotics, so it is very useful clinically.1 Therefore, the determination of rifampicin has attracted much attention. From now on, techniques for the determination of rifampicin have been primarily based on spectrophotometry,2 double-wavelength thin-layer scan,3 chemiluminescence,4 high performance liq…

| Abstract: | A new flow‐injection electrogenerated chemieluminescence (ECL) method for the determination of rifampicin was developed. The method is based on the sensitizing effect of rifampicin on the weak ECL signal of electrochemical oxidation of luminol on the surface of the platinum flake electrode in the medium of 0.02 mol L?1 Na2B4O7. This ECL response is in the range of 1.0 10–4.0 10?‐1 mol L?1 rifampicin with a detection limit of 8.0 10?‐9 mol L?1. The relative standard deviation is 1.8%. This method has been applied successfully to the determination of rifampicin in capsule. ocustilla and urine samples. |
