UiO-66 (Zr-MOF): Synthesis, Characterization, and Application for the Removal of Malathion and 2, 4-D from Aqueous Solution

UiO-66 (Zr-MOF) metal-organic framework was successfully synthesized by the solvothermal method and characterized using FTIR, PXRD TGA. Its ability to remove Malathion, 2,4-Dichlorophenoxyacetic acid (2,4-D) a mixture of two from an aqueous solution studied. Effects different experimental parameters (pH, adsorbent dose, contact time, speed agitation initial pesticide concentrations) were Adsorption isotherm study revealed that equilibrium data well fitted Freundlich, Langmuir Jovanovic models. Similarly, kinetics showed pseudo-first-order model gave best fitting. Thermodynamic indicated adsorption process spontaneous exothermic. To evaluate matrix effect, tap water samples spiked with standard solutions analytes recoveries in range 70–120% obtained. Based on findings present study, could be taken as promising for removal pesticides
