Modeling and simulation of batch adsorption of the organic dye methylene blue (MB) by modified metal-organic framework-5 (MOF-5) were investigated. The reported data on the adsorption of MB dye onto Wells-Dawson acids (H₆P₂W₁₈O₆₂)-immobilized MOF-5 were employed. The film-pore diffusion model was developed based on external mass transfer coefficient and pore diffusion coefficient that govern the mass transfer process in batch organic dye adsorption. Applying the estimated parameters, the MB adsorption by using modified MOF-5 was examined to evaluate the effects of MOF-5 modification, initial dye concentration, temperature, and the dosage of adsorbent. The adsorption capacity of modified MOF-5 (H₆P₂W₁₈O₆₂/MOF-5) was higher than pure MOF-5. Besides, a lower initial MB dye concentration, higher temperature, and lower adsorbent dosage resulted in higher MB dye adsorption capacity.

使用改性金属有机框架 5 模拟批量有机染料吸附

研究了改性金属有机骨架 5 (MOF-5) 对有机染料亚甲蓝 (MB) 的批量吸附建模和模拟。使用了关于 MB 染料吸附到 Wells-Dawson 酸 (H ₆ P ₂ W ₁₈ O ₆₂ ) 固定的 MOF-5 上的报告数据。膜孔扩散模型是基于控制批量有机染料吸附中传质过程的外部传质系数和孔扩散系数开发的。应用估计的参数，检查使用改性 MOF-5 对 MB 的吸附，以评估 MOF-5 改性、初始染料浓度、温度和吸附剂用量的影响。改性MOF-5 (H ₆ P₂ W ₁₈ O ₆₂ /MOF-5)高于纯MOF-5。此外，较低的初始 MB 染料浓度、较高的温度和较低的吸附剂用量导致较高的 MB 染料吸附容量。
