为比较不同腐殖质组分对吸附态铵态氮流失量的影响，采用平衡吸附法研究了不同腐殖质组分有机矿质复合体对铵态氮的富集特征。结果表明，不同腐殖质组分高岭石有机矿质复合体对铵态氮的富集系数（ Er ）从大到小依次为胡敏酸－高岭石有机矿质复合体（1?26）、胡敏素－高岭石有机矿质复合体（1?14）和富里酸－高岭石有机矿质复合体（1?01）；不同腐殖质组分蒙脱石有机矿质复合体对铵态氮的Er从大到小依次为胡敏酸－蒙脱石有机矿质复合体（1?22）、胡敏素－蒙脱石有机矿质复合体（1?13）和富里酸－蒙脱石有机矿质复合体（1?03）。作为硬炭（ hard carbon）的胡敏酸和胡敏素胶结的玻璃态胶体中存在的孔隙填充方式吸附铵态氮是导致胡敏酸和胡敏素有机矿质复合体对铵态氮富集系数增大的重要原因。

In order to explore effects of different humus components on loss of adsorptive ammonia?nitrogen, characteristics of the enrichment of ammonia?nitrogen by different organo?mineral complexes, components of humus were investigated through a batch experiment of equilibrium adsorption. Results indicate that in terms of ammonia?nitrogen en?richment coefficient, the organo?kaolinite complexes in humus displayed an order of humic acid?Kaolinite>humin?Kaolin?ite > fulvic acid ?Kaolinite, being 1?26, 1?14 and 1?01, respectively;and the organo?Montmorillonite complexes did an order of humic acid?Montmorillonite > humin?Montmorillonite > fulvic acid?Montmorillonite, being 1?22, 1?13 and 1?03, respectively. The adsorption of filling of ammonia?nitrogen into pores existing in the glassy colloids cementing humic acids and humin, rated as hard carbon, is the major cause leading to higher ammonia?nitrogen enrichment coefficient of humic and fulvic acids?mineral complexes.
