The hydrothermal technique plays a vital role in adsorption studies as it can improve the surface nature of adsorbent materials. The present investigation is focused on the fabrication of a higher valence zirconium (Zr4+) coordinated fumaric acid (Fu) (Zr@Fu)-based metal–organic framework (MOF), namely Zr@Fu MOF composite for nutrients (nitrate (NO3−) and phosphate (PO43−)) removal from water. The prepared Zr@Fu MOF composite possesses the enhanced nitrate and phosphate sorption capacities (SCs) of 43.97 and 56.41 mg g−1 respectively at 30 min. The adsorption responsible parameters, such as contact time, pH, dosage, temperature, and co-anions were optimized in a batch mode. The synthesized MOFs were characterized using numerous instrumentation techniques, such as FTIR, BET, SEM and EDAX studies. The nature, order and feasibility of the adsorption were examined using isotherms, kinetics and thermodynamic parameters. The SCs of the Zr@Fu MOF composite towards NO3− and PO43− were compared with the reported adsorbents in the market. The reuse recovery and field applicability studies of Zr@Fu MOF composite were also performed.

易于制造可调谐的富马酸锆多孔金属有机框架，可保留水中的养分
水热技术在吸附研究中起着至关重要的作用，因为它可以改善吸附材料的表面性质。目前的研究集中于制造更高价的锆（Zr 4+）配位的富马酸（Fu）（Zr @ Fu）基金属-有机骨架（MOF），即用于营养物（硝酸盐（ NO 3 - ）和磷酸（PO 4 3-））从水中除去。制备的Zr @ Fu MOF复合材料具有增强的硝酸盐和磷酸盐吸附能力（SCs）分别为43.97和56.41 mg g -1分别在30分钟 以批处理方式优化了吸附负责的参数，例如接触时间，pH，剂量，温度和共阴离子。使用多种仪器技术（例如FTIR，BET，SEM和EDAX研究）对合成的MOF进行了表征。使用等温线，动力学和热力学参数检查了吸附的性质，顺序和可行性。朝向NO Zr的@傅MOF复合的SCS 3 -和PO 4 3-，在市场所报告的吸附剂进行了比较。还进行了Zr @ Fu MOF复合材料的重用回收率和现场适用性研究。
