摘要：

A method is described for analysis of hydrogen peroxide directly by CZE in borate buffer based on its absorption in UV light at 185 nm, without reaction with dyes. The absorption at 185 nm was about 3.5 times better than that at 214 nm. Hydrogen peroxide was generated enzymatically from glucose in aqueous solutions and in serum and was removed by the catalase enzyme. To improve the sensitivity of detection, samples were concentrated on the capillary based on stacking by ACN. The method is rapid (similar to 7 min) and specific.
