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.
