Free chlorine and a combined organic N-chloramine (3-chloro-4,4-dimethyl-2-oxazolidinone, compound 1) were compared for efficacy as disinfectants against an admixture of cysts of Giardia lamblia and Giardia canis in water solution under a variety of test conditions; variables were pH, temperature, and water quality. In general, compound 1 was found to reduce the giardial excystation in the solutions at lower concentration or shorter contact time at a given total chlorine concentration than did free chlorine.
在各种测试条件下，比较了游离氯和一种有机结合的N-氯胺（3-氯-4,4-二甲基-2-恶唑烷酮，化合物1）作为消毒剂对水溶液中兰氏贾第鞭毛虫和犬贾第鞭毛虫混合包囊的消毒效果；变量包括pH值、温度和水质。一般来说，发现在给定的总氯浓度下，化合物1在较低浓度或较短接触时间时比游离氯更能减少溶液中贾第鞭毛虫的脱囊。
