摘　　要：近年来,生物炭对减少水体环境中的硝酸盐污染、土壤氮素淋溶损失等问题的研究正日益受到国内外研究者的关注。通过对目前国内外生物炭对NO-3-N的吸附研究文献进行总结分析,得出了生物炭对NO-3-N的吸附机理及其影响吸附效果的因素等,指出生物炭对吸附NO-3-N的可行性,并提出未来该研究领域中尚存的薄弱环节包括吸附机理的模型建立、工业水处理的应用研究、提高吸附效率的改性方法、生物炭吸附材料的解吸及再生利用、对土壤理化性质的影响及其作用机理等。The research on decreasing nitrate in water and the N（NO3^--N）leach in soil using biochar,has attacted great attention at home and abroad in recent years.This paper summarizes the adsorption mechanism and the factors which influence the adsorption effectiveness for NO3^- of the biochar in water and soil according to a large amount of literature at home and abroad.On the basis of reviewing such literature,the feasibility of adsorption for nitrate using biochar has been concluded.A few themes were thus proposed for the further study in adsorption of nitrate：modeling adsorption mechanism,the industrial application research on water treatment,modification method for improving the efficiency of adsorption,desorption and regeneration of adsorbent for biochar,the physical and chemical properties effect on soil and the adsorption mechanism when amending biochar.
