Experiment on the Adsorption Potential of Modified Corncobs for Nitrite Removal from Seawater

摘要

Efficient nitrite adsorbent materials made from corncobs through physical and chemical modification were used to adsorb nutrite in seawater. In this experiment, the effect of time and modification on corncobs adsorption capacity was studied. It shows that the removal ratio for nutrite presented an increasing tendency over time and reached the highest after 270 minutes, the removal ratio of modified corncobs reached 52.1%, which improved 10% compared with unmodified corncobs. Besides, through contrastive experiment with some other nitrite adsorbent materials, modified corncobs are proved to have the highest removal ratio for nutrite.
