Present study has been designed to govern the usage of nanocomposite of Si₃N₄ with trimetallic oxide nanoparticles of Ag, Mg and Fe (AgO/MgO/FeO@Si₃N₄) for the tetracycline (TC) removal from aqueous solution. Characterization techniques such as SEM, TEM, XRD, FTIR, XPS and BET were employed for analysing the successful fabrication of AgO/MgO/FeO@Si₃N₄ nanocomposite. Adsorption process has been found to be dependent upon the surface properties of AgO/MgO/FeO@Si₃N₄ nanocomposite (such as charge, functionality, etc), concentration of TC, solution pH and contact time. As determined from the isotherm studies, surface of AgO/MgO/FeO@Si₃N₄ nanocomposite has been found to be energetically heterogeneous in nature as the data fitted well to Freundlich isotherm. Maximum adsorption capacity of AgO/MgO/FeO@Si₃N₄ nanocomposite has been found to be 172.41 mg/g. Pseudo-second order kinetic model successfully explained the rate studies of TC adsorption. Also, reusability study of AgO/MgO/FeO@Si₃N₄ nanocomposite has also been carried out. In short, the present study could determine an effective way for the removal of toxic pollutants from the wastewater system.

目前的研究已经设计为控制Si ₃ N ₄纳米复合物与Ag，Mg和Fe的三金属氧化物纳米粒子（AgO / MgO / FeO @ Si ₃ N ₄）的使用，以从水溶液中去除四环素（TC）。采用SEM，TEM，XRD，FTIR，XPS和BET等表征技术对AgO / MgO / FeO @ Si ₃ N ₄纳米复合材料的成功制备进行了分析。已经发现吸附过程取决于AgO / MgO / FeO @ Si ₃ N ₄纳米复合材料的表面性质（例如电荷，官能度等），TC浓度，溶液pH和接触时间。根据等温线研究确定，AgO / MgO / FeO @ Si的表面已经发现₃ N ₄纳米复合材料在能量上是异质的，因为该数据非常适合Freundlich等温线。发现AgO / MgO / FeO @ Si ₃ N ₄纳米复合材料的最大吸附容量为172.41 mg / g。伪二级动力学模型成功地解释了TC吸附速率的研究。此外，还进行了AgO / MgO / FeO @ Si ₃ N ₄纳米复合材料的可重复使用性研究。简而言之，本研究可以确定从废水系统中去除有毒污染物的有效方法。
