Zeolite-based-fertilizers can be obtained by adsorbing plant nutrients to their porous structure. In this research, the natural zeolite (0-200 μm) from Gordes/Türkiye was combined with NHNO in a 1:4 solid ratio and processed at 200 °C for 2-24 hours and characterized with diffrent techniques. The optimal synthesis time was 8 hours, yielding a fertilizer with 5.06% nitrogen content. The zeolite-based-fertilizer exhibited a clinoptilolite structure similar to the raw zeolite but demonstrated a greater percentage of mass loss in the DTA/TGA analyses and distinct nitrate peaks in the FTIR spectra, attributable to ammonium nitrate adsorption. The BET results showed a decrease in the BET surface area after the adsorption of NHNO onto natural zeolite, with measured values of 34.56 m²/g for natural zeolite and 19.24 m²/g for zeolite-based-fertilizer. The results indicate successful synthesis of a zeolite-based nitrogen fertilizer with potential compatibility with Green Deal goals. .
基于沸石的肥料可以通过将植物养分吸附到其多孔结构中获得。在本研究中，将来自土耳其戈尔代斯的天然沸石（0-200μm）与硝酸铵按1:4的固比混合，在200°C下处理2-24小时，并采用不同技术进行表征。最佳合成时间为8小时，得到的肥料含氮量为5.06%。基于沸石的肥料呈现出与天然沸石相似的斜发沸石结构，但在差示热分析/热重分析中显示出更大的质量损失百分比，在傅里叶变换红外光谱中显示出明显的硝酸盐峰，这归因于硝酸铵的吸附。比表面积测定结果表明，天然沸石吸附硝酸铵后比表面积减小，天然沸石的测量值为34.56m²/g，基于沸石的肥料为19.24m²/g。结果表明成功合成了一种与绿色协议目标具有潜在兼容性的基于沸石的氮肥。
