BI沸石对氨氮的吸附与解吸

Adsorption and Desorption of BI Zeolite to Nitrogen-ammonia

研究了BI沸石对氨氮动态和静态的吸附与解吸特性.试验表明,在静态和动态两种情况下,BI沸石对氨氮的吸附效果良好,并且动态吸附容量比静态吸附容量大,有利于机械化生产沸石氮肥.静态实验数据表明,沸石在土壤中,解吸速率较慢,有利于作物对肥料的吸收而提高肥料利用率,因此,沸石在土壤保水、提高肥效方面有重要的开发价值.

The properties of adsorption and desorption of BI zeolite are studied under the static and dynamic states. Experimental results show that the effect of absorption of BI zeolite for nitrogen-ammonia is very good in the above two situations, moreover, capacity of former is more than that of later which is beneficial to mechanize producing zeolite nitrogenous fertilizer. Static experiments show that desorption of BI zeolite is slower,which help to improve adsorption of fertilizers.It is of great value in keeping water in the soil and in raising the efficiency of fertilizers.
