The Preparation and the Research of Copper-Chelex Chitosan for Removal Ammonia-Nitrogen from the Drinking Water

Abstract:

In order to remove ammonia-nitrogen from drinking water and reduce its threat to human health, Copper-chelex chitosan that is to be the new ammonia-nitrogen remover was prepared by chelating chitosan with copper acetate. In this paper, we measure the effect of this remover with pH= 7.5, 8.5, 9.5 and the concentration of ammonia-nitrogen, such as 1.5mg/L,2.5mg/L,5mg/L,10mg/L and 100mg/L. From the result of this experiment, we draw a conclusion that the removal efficiency of ammonia-nitrogen is about 80% when the pH is greater than 7.5 and the water inflow concentration of ammonia-nitrogen is 100mg/L. as the initial concentration ammonia-nitrogen is increasing, the removal rate is improved regularly.
