- Synthesis of Orange IV Modified β-Cyclodextrin and Study of Its Supramolecular Recognition
橙黄IV修饰β-环糊精的合成及其超分子识别作用的研究 - It is found that in a HAc-NaAc buffer at pH4.6, the oxidizing decolourization of Orange IV by hydrogen peroxide is catalyzed by Cu(ⅱ) ion. Thus a new kinetic spectrophotometric method for the determination of trace copper was developed.
在pH4.6的乙酸-乙酸钠缓冲介质中，铜（Ⅱ）与过氧化氢氧化橙黄Ⅳ的褪色反应具有强烈催化作用，由此提出了催化动力学光度法测定痕量铜的新方法。
