Abstract
Nitrogen in water is mainly composed of ammonium, nitrite and nitrate, and which can cause eutrophication. A lot of efforts were made to remove them and the accompanying efforts have been made for the development of analytical methods. Rapid and on site detection methods are required for the analysis of pollutants in water system. Thus, we focused on the development of analytical method for nitrite, and the feasibility study on the nitrite analysis by PVC adsorbent columns coated with BCDMA, Biphenyl and methanol. The adsorbents could effectively adsorb mixed reagent in the range of 4 to 20 for nitrite detection and show linear relationship with color band length. The adsorbance was influenced by pH.
