The use of chlorine dioxide to disinfect drinking water and ameliorate toxic components of wastewater has significant advantages in terms of providing safe water. Nonetheless, significant drawbacks toward such usage remain. These drawbacks include the fact that toxic byproducts of the disinfection agents are often formed, and the complete removal of such agents can be challenging. Reported herein is one approach to solving this problem: the use of α-cyclodextrin to affect the product distribution in chlorine dioxide-mediated decomposition of organic pollutants. The presence of α-cyclodextrin leads to markedly more oxidation and less aromatic chlorination, in a manner that is highly dependent on analyte structure and other reaction conditions. Mechanistic hypotheses are advanced to explain the cyclodextrin effect, and the potential for use of α-cyclodextrin for practical wastewater treatment is also discussed.

就提供安全水而言，使用二氧化氯对饮用水进行消毒并改善废水中的有毒成分具有明显的优势。然而，仍然存在针对这种用法的明显缺点。这些缺点包括以下事实：经常会形成消毒剂的有毒副产物，而彻底去除此类消毒剂可能会带来挑战。本文报道的是解决该问题的一种方法：使用α-环糊精影响二氧化氯介导的有机污染物分解中的产物分布。α-环糊精的存在以高度依赖于分析物结构和其他反应条件的方式导致明显更多的氧化和更少的芳族氯化。提出了机械假设来解释环糊精的作用，
