Teas and traditional herbs are taken as health remedies in most cultures worldwide. Plants often used in the manufacture of teas and herbal remedies can comprise carcinogenic contaminates, such as nitrates, nitrites and bromate ions. In the present study, a quick method was applied for the simultaneous determination of nitrate (NO₃⁻), nitrite (NO₂⁻) and bromate (BrO₃⁻) ions in some selected plants and tea samples using capillary electrophoresis and a Box–Behnken response surface design for method optimization.

毛细管电泳法同时测定某些选定植物中的硝酸根、亚硝酸根和溴酸根离子

在全球大多数文化中，茶和传统草药被视为健康疗法。经常用于制造茶和草药的植物可能包含致癌污染物，例如硝酸盐、亚硝酸盐和溴酸盐离子。在本研究中，采用一种快速方法，使用毛细管电泳和 Box– 同时测定某些选定植物和茶样品中的硝酸盐 (NO ₃ ⁻ )、亚硝酸盐 (NO ₂ ⁻ ) 和溴酸盐 (BrO ₃ ⁻ ) 离子。用于方法优化的 Behnken 响应曲面设计。
