硫酸改性沸石中主要交换性阳离子动态变化研究

Study on the main exchangeable cations dynamic change in the sulfuric acid modified zeolite

近年来天然沸石在农业中得到了广泛的应用。利用硫酸对天然沸石进行活化试验,通过对其1年的动态监测,分析沸石中对植物生长有重要影响的交换性K+、Ca2+、Mg2+、Na+以及阳离子交换量动态变化,以得到硫酸和沸石反应后各养分的动态变化,为改性后沸石生产农作物矿物肥提供理论依据。

in recent years, natural zeolite has been widely applied in agriculture.The experiment mainly activation assay on natural zeolite by sulfuric acid, and then through monitoring exchangeable cations （K＋, Ca2＋, Mg＋, Na＋）and cation exchange capacity in zeolite of the dynamic changes within a year, these cations have an important impact on plant growth. The dynamic changes in sulfuric acid modified zeolite can supply theoretical basis for that as crops of mineral fertilizer.
