%X Bamboo-carbon was modified by nitric acid to enhance its absorption capacity.The effects of various parameters such as absorbent dosage,absorption time,absorption temperature and pH on ammonia nitrogen absorption efficiency of bamboo-carbon were investigated,meanwhile the absorption mechanism of ammonia nitrogen by modified bamboo-carbon was studied.The results showed that the ammonia nitrogen absorption capacity of bamboo-carbon was affected by both chemical and structural properties of the bamboo-carbon surface.Compared with bamboo-carbon,the surface properties of modified bamboo-carbon such as oxygen-containing functional groups,specific surface areas,total pore volume were higher,ammonia nitrogen removal ratio was increased from 20.1% to 82.2%,absorption equilibrium time decreased from 6 h to 4 h.Absorption of ammonia nitrogen by bamboo-carbon could be described by Freundlich equation.Furthermore,the absorption performance of modified bamboo-carbon was obviously affected by such parameters as absorbent dosage,absorption time,absorption temperature and pH.
