| Abstract: | This paper gives a new way to determine the COD in reverse osmosis(RO) water. Through contrast test and statistic analysis for one year or more, the author discovered that no obvious difference in determining COD of RO product water using both methods of ultraviolet absorption spectrometry and acidic polassium permanganate process, moreover the former's accuracy is higher and can meet the requirements of pure water production and quick-determination in scientific research. |
