Abstract According to the research, zeolitic imidazolate framework (ZIF‐67) and graphene oxide (GO) nanosheets were synthesized with a guar gum (GG) biopolymer substrate form two‐component hybrid biocomposites: GO/ZIF‐67 (GOZ), GG/ZIF‐67 (GZ), three‐component GO/GG/ZIF‐67 (GGZ) polymer. These composites used adsorb malachite green (MG) cationic dye from an aqueous solution at room temperature. The chemical fractions, morphological structural properties of biocomposites determined using Fourier transform infrared spectrometer (FTIR), scanning electron microscope (SEM), X‐ray diffraction (XRD), Brunauer–Emmett–Teller (BET) analyses. adsorption MG was carried out on polymer under different experimental conditions. high surface area GZ, GOZ, GGZ 1362.89, 754.89, 833.67 m 2 g −1 , respectively, total pore volume 0.90 cm 3 for 0.51 GOZ GGZ, respectively. removal pollutant follows pseudo‐second order model Langmuir model. mechanism involves hydrogen bonding, π‐π stacking, electrostatic interactions. showed maximum efficiency 66.6%, 74.4%, 90.1%, data show that after cycles 90%, 86%, 82%.

Published: Feb. 27, 2025

Abstract This study explored the use of garlic as a natural biosorbent to remove anthraquinone dyes (Blue Bemacid (BB), Red (RB), Yellow (YB), Orange (OB)) from wastewater. Virtual screening and molecular docking showed high dye‐garlic binding affinities exceeded those calculated for native ligand during re‐docking. The experiments successfully removed 86.14% 78.17% Blue Bemacid. was done using 0.1 g garlic, pH 2, dye concentration 50 ppm, contact time 10 min. Bland–Altman analysis confirmed measurement method agreement. results provide insights into physical chemical mechanisms removal by biosorbent, like garlic. Key findings include superior performance over work demonstrates potential natural, low‐cost materials wastewater treatment applications.
