Sažetak
Nitrogen compounds discharged into the environment affects the suitability of river water for human use and causing problems such as the eutrophication of rivers and deterioration of water sources. Furthermore, nitrates can also form nitrosamines and nitrosamides, potentially carcinogenic compounds. Therefore, the removal of nitrogen from wastewater is a major objective for pollution control. Adsorption and ion exchange are reliable methods for removing nitrate from wastewater. Rapid increase in volume and types of agricultural waste materials, has become a burden issue. Agricultural biomass have been investigated as adsorbents for pollutant removal from wastewater. They are widely available and cheap. Many research has been made on agricultural wastes for the removal of nitrate from water. Some of these materials are rice hull, sugarcane bagasse, coconut shells, wheat straw, almond shell, giant reed and many more. Agricultural wastes as adsorbents for nitrate showed low or moderate adsorption capacities, however, chemical and physical modifications can increase their adsorption capacities. Different modification methods have been examined, but amine grafting method showed remarkable results for the adsorption of nitrate from water. This work studied different waste materials and modification methods for nitrate removal from water and wastewater.
