This paper describes the synthesis of a promising material and evaluates the suitability of a metal-organic framework (MOF-199) for purifying toxic methylene blue (MB) dye wastewater via an adsorption process. (MOF-199) is considered much better than traditional adsorbents. The research focused on determining the adsorption characteristics and dye removal effectiveness with MOF-199, where several factors were studied, including dye concentration, contact time, amount of adsorbent, and PH. The highest observed dye removal efficiency was 97.21% when the PH was 7.5, and the reaction duration was 90 minutes. This was achieved by adding 0.2 g of MOF-199 to a dye solution containing 20 mg/L methylene blue. The adsorption process was evaluated by "Langmuir, and models". As the strong correlation factor (R2 = 0.9989) indicates, The Freundlich isotherm. "A pseudo-second-order" kinetic model was the best describes the adsorption methylene blue by MOF-199. This indicates that the main mechanism of dye removal is chemisorption. Finally, the MOF-199 material can have remarkable reusability as an adsorption material for (MB) and subsequent efficiency of MOF-199 exhibited a reduction of 14.43% after undergoing four cycles, compared to its initial state. Yet, it remained at a commendably high level.
