【Abstract】 NH 3-N is one of the nutritious matters in wastewater. A good adsorbent is obtained which can be easily regenerated without second contamination by physical-chemical and chemical methods. The result of treatment satisfies the state standard. With the study, the sulphonated coal prepared from Huangbaici high-sulfur coal is considered as excellent adsorbent, dilute sulfuric acid a good regenerant, for dealing with NH 3-N-containing wastewater. The influences of temperature, adsorption time, sulphonated coal amount and pH value in wastewater on NH 3-N adsorption of the activated sulphonated coal have been studied. The mechanism for the sulphonated coal adsorbing NH 3-N from wastewater is discussed with results of FT-IR given.更多还原
