已经证明，游离氯和3-氯-4,4-二甲基-2-恶唑烷酮（化合物I）的混合物是一种有效的水消毒剂。混合物中的少量游离氯可提供快速的初始消毒，而大量化合物I可在较长时间内保持消毒效果。本研究中使用的混合物对金黄色葡萄球菌的几种挑战进行了30天或更长时间的消毒。在某些情况下，游离氯和化合物I的作用可能是协同的。包括26个参考文献、表格和图表。

It has been demonstrated that a mixture of free chlorine and 3-chloro-4,4-dimethyl-2-oxazolidinone (compound I) is an effective water disinfectant. A small amount of free chlorine in the mixture provides rapid initial disinfection, with a larger amount of compound I maintaining disinfection efficacy over a long period of time. The mixtures used in this study disinfected against several challenges of Staphylococcus aureus for 30 or more days. In some cases the actions of the free chlorine and compound I may have been synergistic. Includes 26 references, table, figure.
