摘    要:采用室内分析的方法,研究天然沸石及改性沸石对NH4+的吸附解吸特性。结果表明,K-沸石、Ca-沸石、Mg-沸石和Ba-沸石对NH4+吸附量及解吸量均比天然沸石高,其中K-沸石最高,其它三者相近。H-沸石与天然沸石相比,在低浓度时比天然沸石的吸附(解吸)量高,但是在高浓度时吸附(解吸)量则降低。改性沸石与天然沸石相比,不仅提高了NH4+的吸附,同时还促进了NH4+的解吸,说明K-沸石、Ca-沸石、Mg-沸石和Ba-沸石,既具有较强的保氮能力,又具有较高的氮素供给能力,在生产实践中有着广阔的应用前景。

关 键 词:沸石  改性沸石  NH4+  吸附  解吸

Abstract:Absorption and desorption of NH4+ by natural zeolite and modified zeolite is studied.Compared with natural zeolite, K – zeolite、Ca – zeolite、Mg-zeolite and Ba-zeolite to the NH4+ is stronger absorption and desorption capacity,and K – zeolite is the greatest. To H-zeolite, low concentration is higher than the natural adsorptive(desorptive) capacity,but high concentration is lower then the natural adsorptive(desorptive).The modified zeolite not only may enhance the adsorption of NH4+, but also may promoted the desorption of NH4+. It shows that modified zeolite not only has strongly guarantees the nitrogen ability, but also high nitrogen supplying ability. So it has broad application prospect in the agricultural practice.
Keywords:NH4
