摘　　要：以无机和有机盐为改性剂,硫酸铵溶液为吸附剂,研究了南阳麦饭石改性前后对铵氮的吸附,结果表明用硫酸钠改性吸附效果最好。探讨了硫酸钠作为改性剂时不同的改性时间、温度、浓度、用量及pH值等条件对南阳麦饭石改性后吸附性的影响。This paper deals with the research on ammonia nitrogen adsorption of Nanyang medical stone pre-and post-modified by inorganic and organic salt solution with ammonium sulfate solution as the adsorption reagent. Results showed that Nanyang medical stone modified by Na2SO4 produced the best adsorption effect. Also, study of the influence of modification temperature and time, concentration. dosage , pH value of Na2SO4 solution and others on adsorption performance of Nanyang medical stone using sodium sulfate as modifier.
