Since the beginning of industrial revolution, uncontrolled discharge wastewater from textile and dyeing industries into water bodies is environmentally challenging to humans ecosystem. Using Cola nitida (CN) leaves extract, Taguchi optimization method was successfully applied achieve green synthesis iron oxide nanoparticles (CN–Fe2O3NPs). Textural properties, nature surface functional groups, crystalline structure morphology CN–Fe2O3NPs were studied. The performance tested for methylene blue (MB) methyl orange (MO) removal wastewater. optimal area 125.31 m2/g achieved using CN extract volume (10 mL), precursor concentration (2 M), contact time (30 min) calcination temperature (600 °C). Overall, had highest effect than other parameters. characterization revealed presence hematite with Fe–O, Fe–O–Fe groups a regular-shaped porous material. Furthermore, adsorption capacity 530.406 527.835 mg/g obtained MB MO within 60 min nanoadsorbent dosage (25 mg/L), initial dye (100 mg/L) (50 reusability stability successful reuse after six cycles without any damage as corroborated by fourier transform infrared (FTIR) spectroscopy. experimental data suitably fitted Langmuir isotherm pseudo-second-order kinetic models denoting chemisorption monolayer process. thermodynamic parameters indicate an endothermic spontaneous Hence, high separation effectiveness against molecules good great potential synthesized in purification.

Numerical Recognition System and Ultrasensitive Fluorescence Sensing Platform for Al³⁺ and UO₂²⁺ Based on Ln (III)-Functionalized MOF-808 via Thiodiglycolic Acid Intermediates

ACS Applied Materials & Interfaces, Journal Year: 2023, Volume and Issue: 15(13), P. 16882 - 16894

Published: March 21, 2023

Continuous accumulation of Al3+ in the human body and unintended leakage UO22+ have posed a great threat to health global environment; thus searching an efficient probe for detection is importance. Herein, we designed synthesized two hydrolytically stable Eu3+- Tb3+-functionalized MOF materials Eu@MOF-808-TDA Tb@MOF-808-TDA via thiodiglycolic acid (TDA) intermediates by postsynthetic modification method. Among them, was applied construct numerical recognition systems multiples three four combination fluorescent signals, hierarchical cluster analysis, logical gates. In addition, exhibits good selectivity sensitivity UO22+. The limit calculated be 0.085 ppm 0.082 aqueous solutions, which lower than or close that latest reported Ln-MOFs. Moreover, shows excellent hydrolytic stability luminescence pH range 4-11, further providing solid evidence practical application Tb@MOF-808-TDA. More importantly, mixed matrix hydrogel PVA-Tb@MOF-808-TDA prepared achieve visual Al3+, broadens potential real-world sensing applications.
