Evaluation of Zn Adenine-Based Bio-MOF for Efficient Remediation of Different Types of Dyes

As an eco-friendly material, Zn-adeninate bio-metal-organic framework (bio-MOF) was investigated as efficient adsorbent for both anionic and cationic dyes. The adsorption capability of the synthesized bio-MOF confirmed by its notable surface area 52.62 m2 g−1 total pore volume 0.183 cm3 g−1. profiles direct red 81 (DR-81) methylene blue (MB) dyes were under different operating parameters. optimum dosages 0.5 g L−1 1 MB DR-81 decolorization, respectively. pHPZC 7.2, maximum monolayer capacity 132.15 mg g–1 MB, which decreased to 82.54 dye. Thermodynamic data indicated spontaneous endothermic nature decolorization processes. Additionally, processes in agreement with Langmuir pseudo-second-order kinetic models. could be reused several times high ability. These findings demonstrated that Zn is effective promising material removal from polluted water.
