| Abstract: | This paper deals with the research on ammonia nitrogen adsorption of Nanyang medical stone pre-and post-modified by inor-ganic and organic salt solution with ammonium sulfate solution as the adsorption rengent. 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 per-formance of Nanyang medical stone using sodium sulfate as modifier. |
