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 […]International Water Treatment
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. […]International Water Treatment
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 […]International Water Treatment
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 […]International Nuclear Industry
Tackling the difficult questions: Ashley Malin, PhD.
“But in the years following my healing, I kept my promise” In this video, Dr. Ashley Malin recounts her path to becoming a public health scientist and psychologist, facing a life-altering disease along the way. Watch to learn how Dr. Malin’s determination led to publishing research in an under-studied field, linking low-level sodium fluoride exposure […]International
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 […]International Perfluorinated chemicals
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 […]International Batteries
Global thirst for electricity is fuelling the rise of a potent greenhouse gas
A construction boom for electric power plants in countries such as China has contributed to a spike in emissions of a greenhouse gas used to insulate electrical equipment such as circuit breakers. Credit: Hu Weiguo/VCG via Getty Emissions of sulfur hexafluoride soared over the 40 years to 2018, despite some countries’ efforts to curb […]International Greenhouse/Ozone Gases
The increasing atmospheric burden of the greenhouse gas sulfur hexafluoride (SF6)
Abstract We report a 40-year history of SF6 atmospheric mole fractions measured at the Advanced Global Atmospheric Gases Experiment (AGAGE) monitoring sites, combined with archived air samples, to determine emission estimates from 1978 to 2018. Previously we reported a global emission rate of 7.3±0.6 Gg yr1 in 2008 and over the past decade emissions have […]International Greenhouse/Ozone Gases
Rapid destruction of sarin surrogates by gas phase reactions with focus on diisopropyl methylphosphonate (DIMP).
Note from FAN: The molecular structure of Sarin: Abstract Rapid destruction of stockpiles of sarin and other chemical weapon agents (CWA) requires understanding and quantitative description of the relevant chemical reactions. Rapid reactions at elevated temperatures are of particular interest for prompt agent defeat scenarios. Diisopropyl methylphosphonate (DIMP) is a sarin surrogate particularly well suited […]International Chemical Weapons
