Modeling defluoridation of real-life groundwater by a green adsorbent aluminum/olivine composite: Isotherm, kinetics, thermodynamics and novel framework based on artificial neural network and support vector machine
Highlights AOC can efficiently remove fluoride from real-life groundwater up to 87.5%. Freundlich and Elovich models demonstrated adsorption isotherm and kinetics. Adsorption thermodynamic reflects spontaneous, endothermic, physisorption reaction. Benchmarking sorption process of synthetic and real-life water for field simulation. Neural network performed as better prediction model than support vector machine. Abstract The kinetic, isotherm, and […]

A holistic study on fluoride-contaminated groundwater models and its widespread effects in healthcare and irrigation
Abstract Groundwater is a key resource in the world. Its importance is often undermined, despite the various applications which include irrigation, drinking, sanitation, and industrial uses. One of the contaminants of groundwater is fluoride or the fluorine ion. Fluoride is a common pollutant of water, carrying potential benefits and costs to various sectors. Fluoride contamination […]

Highly efficient fluoride removal from water using 2D metal-organic frameworks MIL-53(Al) with rich Al and O adsorptive centers
Highlights 2D MIL-53(Al) was prepared by using the solvothermal method. 2D MIL-53(Al) was exposed to enhance the adsorption of fluoride. 2D MIL-53(Al) had good adsorptive performance at a wide range of pH. DFT calculation and experiments were investigated for removing fluoride. Abstract In this study, metal-organic framework MIL-53(Al) was synthesized and studied to understand the […]

Interaction-based ion selectivity exhibited by self-assembled, cross-linked zwitterionic copolymer membranes
Significance The separation of ions is challenging yet crucial for providing access to safe water resources as well as recovering valuable ions from water and wastewater. Yet, membranes rarely exhibit selectivity between ions of similar charge and size. We demonstrate that membranes, prepared by a fully scalable method that uses self-assembling zwitterionic copolymers, exhibit exceptional […]

Effective fluoride removal from brackish groundwaters by flow-electrode capacitive deionization (FCDI) under a continuous-flow mode
Highlights Utilizing FCDI to treat fluoride-contaminated brackish groundwater is quite effective. SCC was the most advantageous among the three operational modes of SCC, SC and ICC. F– was preferentially removed compared to Cl– with a high ion selectivity achievable. Steady-state effluent F– and Cl– concentrations versus current are greatly different. Abstract Herein, we demonstrated the […]

Insights into the mechanism of fluoride adsorption over different crystal phase alumina surfaces
Abstract Activated alumina is the most common adsorbent for purifying fluoride in water, however, little is known so far about the adsorption mechanisms and comparison of adsorption behaviors for F on different crystal phase alumina surfaces, which seriously obstacles the development of high-performance sorbents. Herein, employing the density functional theory approach, we have studied F […]
