| 摘 要： | 研究了紫外光照射下，KNO3对罗丹明B光解的敏化作用．结果表明，KNO3的加入可以显著提高罗丹明B的光降解率，反应液的酸度愈强愈有利于反应的进行，KNO3不仅对罗丹明B的降解有敏化作用，而且还能够直接提供氧化罗丹明B所需要的氧。

| Abstract: | The photosensitization of nitrate to the photooxidation of Rhodamine B under the UV irradation has been studied in this paper.The result showed that the presence of KNO 3 could promote the photooxidation of Rhodamine B markedly.The lower pH value of reaction solution corresponds with the higher reaction rate.KNO 3 not only promotes the degradation of Rhodamine B,but also directly supplys the oxygen to the oxidation of Rhodamine B. |
