Recycled materials were used in three types of green sorption media for nutrient removal and possible recovery in high nutrient-laden agricultural discharge and stormwater runoff. The three types of green sorption media included in this comparative study were two new aluminum-based green environmental media (AGEM) and one existing iron-filings based green environmental media (IFGEM). The corresponding adsorption isotherm, thermodynamics, and kinetics models were simulated based on isotherm studies to determine their removal efficiency and potential for recovery of nitrate, phosphate, and ammonia when used as a soil amendment in crop fields or in a filter for water treatment. AGEM-2 exhibited the shortest contact time required to achieve nutrient removal above 80% with an average of 7 h, followed by AGEM-1 and IFGEM with 10.6 and 28 h, respectively. Natural soil was included as a control and exhibited minimal nutrient removal. Ammonia, which may be recovered as fertilizer for drop fields in a soil-water-waste nexus, was generated by all three green sorption media mixes, therefore indicating their potential for use as soil amendments in agricultural and forested land after engineering filter applications. The kinetics analysis indicated that nitrate adsorption follows pseudo-first-order kinetics, while phosphate adsorption follows pseudo-second-order kinetics. The Gibbs free energy indicated that most of the adsorption reactions proceeded as exothermic. Lastly, a few equilibrium models, including the Langmuir, Freundlich, First Modified Langmuir, Temkin, Jovanovic, and Elovich models, were ranked and three were selected for use with IFGEM, AGEM-1, and AGEM-2, respectively, as below: (1) Langmuir, (2) Freundlich, and (3) First Modified Langmuir, according to three indices.

回收的材料用于三种类型的绿色吸附介质中，以去除养分并在高养分农业排放和雨水径流中进行回收。这项比较研究中包括的三种绿色吸附介质是两种新的铝基绿色环保介质（AGEM）和一种现有的铁基绿色环保介质（IFGEM）。根据等温线研究对相应的吸附等温线，热力学和动力学模型进行了模拟，以确定它们的去除效率以及硝酸盐，磷酸盐和氨在用作农田土壤改良剂或用于水处理的过滤器中的回收潜力。AGEM-2表现出达到80％以上的营养去除率所需的最短接触时间，平均为7小时，其次是AGEM-1和IFGEM，分别为10.6和28小时。包括天然土壤作为对照，并显示出最少的养分去除。三种绿色吸附介质混合物均会产生氨，可将其作为肥料用于土壤-水-废物联系中的滴灌田，因此表明氨在工程过滤器应用后可用作农业和林地土壤改良剂的潜力。动力学分析表明，硝酸盐吸附遵循伪一级动力学，而磷酸盐吸附遵循伪二级动力学。吉布斯自由能表明，大多数吸附反应都是放热的。最后，对包括Langmuir，Freundlich，First Modified Langmuir，Temkin，Jovanovic和Elovich模型在内的一些均衡模型进行了排名，并分别选择了三个模型与IFGEM，AGEM-1和AGEM-2结合使用，如下所示：
