A new magnetic zeolite was prepared by the chemical co-precipitation of Fe²⁺ and Fe³⁺ in the presence of natural Manisa- Gördes clinoptilolite. The adsorption of Basic Blue 41 (BB41) from aqueous solutions on natural and magnetically modified zeolite were studied at 298–323 K in a batch system. Natural and magnetic zeolites were characterized by N₂adsorption-desorption, XRD, FTIR, SEM-EDX and VSM analyses. Compared to natural zeolite, S_BET-specific surface area of ​​magnetic zeolite increased by modification process. XRD pattern and FTIR spectra of magnetic zeolite showed the characteristic Fe₃O₄ peaks. Optimum parameters were determined based on the experimental data by investigating the various parameters such as pH, initial dye concentration, adsorbent dosage, adsorbent particle size, contact time, stirring speed and temperature. Adsorption isotherms and kinetics were analyzed using Langmuir, Freundlich, Dubinin-Radushkevich (D-R), Temkin, Pseudo first order and Pseudo second order models. Adsorption of BB41 on natural and magnetic zeolites well fitted to Langmuir isotherm and pseudo second order kinetic models. The maximum adsorption capacities of natural and magnetic zeolites were determined as 149.25 mg/g and 370.37 mg/g at 323 K, respectively. Thermodynamic analysis revealed a spontaneous and endothermic nature of natural and magnetic zeolites.

在天然 Manisa-Gördes 斜发沸石的存在下，通过 Fe ²⁺和 Fe ³⁺的化学共沉淀制备了一种新型磁性沸石。在 298-323 K 的间歇系统中研究了碱性蓝 41 (BB41) 从水溶液中吸附在天然和磁性改性沸石上。天然沸石和磁性沸石通过 N ₂吸附-解吸、XRD、FTIR、SEM-EDX 和 VSM 分析进行表征。相比天然沸石，S _BET磁性沸石的特异性表面面积增加了修改过程。磁性沸石的XRD图谱和FTIR谱表明Fe ₃ O ₄的特征峰。通过研究各种参数，如pH值、初始染料浓度、吸附剂用量、吸附剂粒径、接触时间、搅拌速度和温度，根据实验数据确定最佳参数。使用 Langmuir、Freundlich、Dubinin-Radushkevich (DR)、Temkin、伪一级和伪二级模型分析吸附等温线和动力学。BB41 在天然和磁性沸石上的吸附非常符合朗缪尔等温线和伪二级动力学模型。在 323 K 下，天然沸石和磁性沸石的最大吸附容量分别为 149.25 mg/g 和 370.37 mg/g。热力学分析揭示了天然沸石和磁性沸石的自发和吸热性质。
