摘要
研究了ＢＩ沸石对氨氮动态和静态的交换、吸附及逆交换、解吸的特性。实验表明：在静态和动态两种情况下，ＢＩ沸石对氨氮的吸附、交换效果良好，在土壤存水、提高肥效方面有重要的开发价值。
The characteristics of exchange and adsorption and reversed exhange of BI zeolite are studied under the static and dynamic states.Experimental results show that in the above two situations the effect of adsorption of BI zeolite for nitrogen ammonia is very good.It is of great value in keeping water in the soil and in raising the efficiency of fertilizers.
