Thermally treated Mytilus coruscus shells for fluoride removal and their adsorption mechanism.
Highlights Calcination increases fluoride adsorption capacity of Mytilus coruscus shells. An increase of calcination temperature from 700 °C to 800 °C increases fluoride removal sharply. The maximum fluoride adsorption capacity of MCS-800 is 82.93 mg/g. Fluoride removal by MCS-800 is achieved via precipitation by forming CaF2. Abstract We evaluated Mytilus coruscus shells (MCS) as an […]

Effective electrochemically controlled removal of fluoride ions using electrodeposited polyaniline-carbon nanotube composite electrodes.
Highlights PANI was electrodeposited onto a CNT-based substrate. PANI was in the partially oxidized emeraldine form and could participate in redox reactions. The PANI-CNTs composite is a promising redox-active electrode material. Enhanced fluoride removal was achieved by electrochemically controlled separation. The selectivity of fluoride over chloride was significantly enhanced. Abstract The objective of this study […]

Equilibrium sorption of fluoride on the activated alumina in aqueous solution.
Removal of fluoride is a desalination technology in which fluoride ions from aqueous solution are adsorbed on suitable adsorbent surfaces. In this study, adsorption potential was performed on both activated alumina (AA) and grinded activated alumina (GAA) by batch experiments for different contact time, pH, fluoride concentration, and adsorbent dose. Results indicated that adsorption occurred […]

Review of fluoride removal from water environment by adsorption.
Highlights Recent developments in fluoride removal from water by adsorption are reviewed. Four technical strategies are proposed for designing of adsorbents. Transfering the adsorption process to industrial scale is urgently needed. Fluoride adsorption and desorption in field condition need further investigation. Abstract Fluoride contamination in water environment due to natural and artificial activities has been […]

Smartphone-based Fluoride-specific Sensor for Rapid and Affordable Colorimetric Detection and Precise Quantification at Sub-ppm Levels for Field Applications
*Read the full article online at https://pubs.acs.org/doi/10.1021/acsomega.0c03465 *Read the full article in pdf at http://fluoridealert.org/wp-content/uploads/mukherjee-2020.pdf Abstract Higher levels of fluoride (F–) in groundwater constitute a severe problem that affects more than 200 million people spread over 25 countries. It is essential not only to detect but also to accurately quantify aqueous F– to ensure safety. […]

Experimental and modeling studies for adsorbing different species of fluoride using lanthanum-aluminum perovskite.
Highlights The hollow Lanthanum-aluminum perovskite was first applied to remove fluoride. The species of F–, HF, HF2– played a more important role at different pH. The Lanthanum sites had more important effect than Aluminum at higher pH. Higher concentrations of fluoride required more Aluminum than Lanthanum sites. Abstract We investigated the adsorption mechanisms for removing […]

CNL announces SMR research partnership with Kairos Power
Canadian Nuclear Laboratories (CNL) has announced a collaboration agreement with US-based Kairos Power, which is working to develop and license fluoride salt-cooled small modular reactor (SMR) technology. The agreement is funded through CNL’s Canadian Nuclear Research Initiative (CNRI) programme and will cover research and engineering of technologies to separate, analyse and store tritium generated through […]

Highly fluorinated chemicals can increase risk for diabetes and coeliac disease in children.
Tuulia Hyötyläinen and Matej Oresic, both researchers in biomedicine, have published two studies on the connection between highly fluorinated chemicals—per- and polyfluoroalkyl substances (PFASs) – and two diseases in children: type 1 diabetes and coeliac disease (US spelling celiac, or gluten intolerance). Both are autoimmune diseases, which arise from an abnormal immune response to the […]

Toyota Announces Fluoride-Ion Solid State Battery, Plans To Stop Selling Prius In Germany
We don’t hear very much about Toyota when it comes to electric cars these days. If it is working on them, it seems to be in no particular hurry to bring them to market. But that doesn’t mean Toyta is not hard at work on developing new batteries for future EVs. This week, researchers at […]
