Chemistry in Pictures: Spotting high fluoride
Credit: Kaleigh Beale Kaleigh Beale remembers when she was in elementary school in Virginia near the Chesapeake Bay some of her classmates had brown stains on their teeth. She was told the stains were a result of too much fluoride in the water. Fluoride is added to most people’s water in the US to prevent […]

Sustainable groundwater treatment technologies for underserved rural communities in emerging economies
Highlights Proven contaminant-specific treatment technologies can treat groundwater sustainably. Technologies are applicable to underserved rural communities. Treatment technologies can be traditional, advanced, or experimental. Enabling environmental and societal factors impact technology acceptance. Water quality parameters may impact or interfere with the technology performance. Abstract Worldwide, about one out of two people depend on groundwater resources […]

Tufts researchers create membrane that filters fluoride out of water
Throughout her career, Ayse Asatekin, associate professor of chemical and biological engineering at Tufts University, has sought to use filters to prevent illness and protect the environment. One mineral that performs this function is fluoride, which results in dental and skeletal fluorosis. Fluorosis is a degradation of bones or teeth that happens when fluoride is […]

Study the Use of Activated Carbon and Bone Char on the Performance of Gravity Sand-Bag Water Filter
Abstract In this study, granulated activated charcoal (GAC) and bio charcoal (BC) is used as a filler in P3 biosand bag filter to study their filtration performance against a range of fluoride impurities from 1-1400 mg/L. A set of experiments are done to analyze the filtration efficiency of the sandbag filter against fluoride impurities after […]

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 […]
