Abstract This study investigates the removal of methylene blue (MB) dye from aqueous solutions using a novel adsorbent, green algae ( Ulva lactuca )-derived biochar-ammonia (NDULB), produced through activation with 85% sulfuric acid and hydrothermal treatment ammonium hydroxide. The characterization NDULB was carried out various techniques, including BET surface area analysis scanning electron microscopy, confirming its high effective porosity for adsorption. work thoroughly examines effects initial MB concentration, solution pH, contact time, dose on adsorption data were modeled Langmuir, Freundlich, Tempkin, Dubinin-Radushkevich isotherms, Freundlich model showing best fit, indicating multilayer heterogeneous surface. According to investigation’s findings, an concentration 200 ppm dosage 1.25 g L −1 , capacity at equilibrium q e ) is 966.31 mg . Kinetic revealed that pseudo-second-order provided fit experimental data, suggesting chemisorption as dominant mechanism. artificial neural network modeling has been studied reported. clarifies multiple variables adsorption, which might lead key insights enlighten development wastewater strategies. demonstrates offers promising, sustainable alternative in treatment, significant implications large-scale application.

In the present study, a zirconium-based metal-organic framework (UiO-66) nanoparticle was synthesized by solvothermal technique and characterized FT-IR, XRD, SEM, BET analyses zeta potential measurements. The effectiveness of UiO-66 nanoparticles for crystal violet (CV) adsorption examined. CV removal process reached equilibrium in 30 min system consistent with pseudo-second-order model, which involves chemical reactions. results were compatible Dubinin-Raduskevich isotherm model. maximum monolayer capacity calculated as 998.18 mg g−1. It deduced that rate low when solution pH acidic, surface charge dominant adsorption. thermodynamic analysis, is exothermic spontaneous. reusability investigated 80.04% obtained even after 5 successful cycles. According to results, have promising rapid efficient dye.
