One form of metal organic frameworks (MOFs) that has been zeolitic imidazolate framework-7 (ZIF-7) is synthesized and characterized and detailed analysis adsorption behavior with Methylene Blue (MB) and Brilliant Green (BG) dyes. Impact of various variables on the method of batch as a solution pH function, MB and BG concentration, ZIF-7 dose, contact time and BG concentration, contact time and the temperature was analyzed and optimal test conditions were identified. Electron microscopy (SEM) has become a common tool for morphology characterization of materials such as ZIF-7. The pores in the substance ZIF-7 have a BET surface area of 94.19 m²g⁻¹ and an average pore size of 2.79 nm, indicating that they are mesoporous. The average pore size of BJH is 1.4477 nm, which is ideal for adsorption. The zero charge (pH_PZC) point of ZIF-7 was computed at 7.5. The adsorption kinetics showed that the action in the pseudo-second processes was adopted by adsorption: order kinetic model and chemisorbing. The parameters of thermodynamics, such as ΔG, ΔS and ΔH, have been specified. The study of adsorption thermodynamics indicated that the reaction was spontaneous and endothermal. The AC electrical conductivity was investigated, with the overlapping large-polaron tunneling (OLPT) model as the operative conduction mechanism.

合成了一种形式的金属有机骨架 (MOF)，即沸石咪唑酯骨架 7 (ZIF-7)，并用亚甲蓝 (MB) 和亮绿 (BG) 染料对其进行了表征和详细分析吸附行为。分析了各种变量对批次方法的影响，如溶液 pH 函数、MB 和 BG 浓度、ZIF-7 剂量、接触时间和 BG 浓度、接触时间和温度，并确定了最佳测试条件。电子显微镜 (SEM) 已成为对 ZIF-7 等材料进行形态表征的常用工具。物质 ZIF-7 中的孔的 BET 表面积为 94.19 m ² g ^{− 1}平均孔径为 2.79 nm，表明它们是介孔的。BJH 的平均孔径为 1.4477 nm，非常适合吸附。ZIF-7的零电荷 (pH _PZC ) 点计算为 7.5。吸附动力学表明，伪秒过程中的作用是通过吸附：有序动力学模型和化学吸附。已经指定了热力学参数，例如ΔG、ΔS和ΔH。吸附热力学研究表明该反应为自发吸热反应。以重叠大极化子隧穿（OLPT）模型作为操作传导机制，研究了交流电导率。
