摘　　要：水中溶解氧不稳定 ,需要现场即时测定。本文旨在研究现场快速测定水中的溶解氧。本研究运用比色分析的朗伯—比尔定律和真空工艺设计 ,将复杂繁琐的实验室测试方法和操作程序有机的融合在测试管中。该测试管能快速、简便地测定水中的溶解氧。测定范围为 0 .0 l～ 12 mg/ l,检出限为 0 .0 lmg/ l。常规法测定时间需要 3～ 5小时 ,而该测试管法仅需 l～ 2分钟 。Dissolved oxygen in water is not stable and need be rapidly detected,Based on the principle of chlorimetric analysis and vacuum process design,complex Detecting method in lab.and operating procedure is associated into a determination tube.The tube can detect dissolved oxygen in water simply and reapidly.The detection range of the tube for dissolved oxygen in water is 0.01～12mg/l.It takes only 1～2 mins to detect a sample by this tube rather than 3～5 hours by the traditional way.The cost of this method cuts heavily.
