Synthesis of ZIF-8 using acetic acid (AA) as polar solvent produced uniform nanoparticles with enhanced adsorption properties for methylene blue removal. Morphology, structural properties and adsorption capacity of ZIF-8 nanoparticles were compared with ZIF-8 produced using N,N-dimethylformamide (DMF) solvent. ZIF-8 (AA) formed uniform nanoparticles with average diameter of 65 nm, significantly smaller than ZIF-8 (DMF) ~ 2 μm. The textural properties of ZIF-8 (AA) showed enhanced mesoporosity consisted of large pore diameter, 2.76 nm and mesopore volume, 0.166 cc/g with moderate 500 m²/g surface area, meanwhile ZIF-8 (DMF) showed microporous structure with high surface area of ~1000 m²/g. The effect of mesoporous features in enhancing methylene blue adsorption was evident by the high adsorption capacity on the ZIF-8 (AA) in comparison to ZIF-8 (DMF). Analysis of the adsorption data has demonstrated that the adsorption of methylene blue followed the pseudo-second order kinetic and the Langmuir model.

使用乙酸（AA）作为极性溶剂合成ZIF-8，可制得均匀的纳米颗粒，具有增强的吸附性能，可去除亚甲基蓝。将ZIF-8纳米颗粒的形态，结构性质和吸附能力与使用N，N-二甲基甲酰胺（DMF）溶剂生产的ZIF-8进行了比较。ZIF-8（AA）形成均匀的纳米颗粒，平均直径为65 nm，明显小于ZIF-8（DMF）〜2μm。ZIF-8（AA）的织构特性显示出增强的介孔性能，包括大孔径，2.76 nm和中孔体积，0.166 cc / g和中等的500 m ² / g表面积，而ZIF-8（DMF）则显示了微孔结构，具有高表面积〜1000 m ²/G。与ZIF-8（DMF）相比，ZIF-8（AA）的高吸附能力证明了介孔特征增强亚甲基蓝吸附的效果。吸附数据的分析表明，亚甲基蓝的吸附遵循拟二级动力学和Langmuir模型。
