Management of Solid Waste Containing Fluoride—A Review
Abstract Technological and economic development have influenced the amount of post-production waste. Post-industrial waste, generated in the most considerable amount, includes, among others, waste related to the mining, metallurgical, and energy industries. Various non-hazardous or hazardous wastes can be used to produce new construction materials after the “solidification/stabilization” processes. They can be used as admixtures […]

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 […]

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 […]
