摘要
水中O2 含量最好采用现场即时测定 ,通过研制一种测试管 ,从而能简便、快速地现场测定水中的O2 。化学法测定时间需要 3～ 5h,而该测试管法仅需 0 5～ 5min 。
The dissolved oxygen (DO) in water needs a field rapid determination.A testing tube is developed,by which the DO in water can be determined easily and rapidly in situ.It takes 2～3hours for a chemical method and only 0.5～5 minutes for the testing tube to test a sample.The analytic cost is reduced greatly.
