This organisation is helping people test the quality of soil and water through a mobile app
Foundation for Environmental Monitoring (FFEM), a non-profit organisation, has developed easy-to-use kits which help in detecting contaminants and chemicals with the help of an Android mobile application. [Some of the parameters that can be measured include pH, Fluoride, Nitrate, Phosphate, Arsenic, and Chlorine.] The ever-swelling urban spaces, rapidly growing industries, and vast migrations in India […]

Rapid and extremely high adsorption performance of porous MgO nanostructures for fluoride removal from water
Highlights Porous MgO nanostructures of different morphology have been synthesized. The synthesized MgO nanostructures showed excellent adsorption capacities for fluoride. The Langmuir adsorption capacity are varied from 5716 to 15,691 mg g-1 at 303 K. The adsorption primarily followed pseudo-second-order kinetic. The adsorbents are reusable for successive use up to fifth cycle. Abstract Fluoride is a […]

Scenario, perspectives and mechanism of arsenic and fluoride Co-occurrence in the groundwater: A review.
Highlights First review on co-occurrence perspectives of Arsenic and Fluoride in the groundwater. As and F co-occurrences is quite common yet concealed owing to one being dominant. Arid areas are more suitable for co-occurrence with few reports in the Alluvium plains. Local hydro-geochemical processes and seasonality greatly affect co-contamination. Co-contamination can have severe health and […]

Removal of fluoride from multicomponent water solutions with the use of monovalent selective ion-exchange membranes
Highlights Electrodialysis (ED) is an efficient method of fluoride removal ED allows to reduce F– ion content below the guidelines for drinking water Energy consumption is influenced by current density and total salt concentration F– ion removal efficiency enhance with the increase of ionic strength of a solution Fluoride deposition on/in the membrane matrix is […]

A framework to model exposure to per- and polyfluoroalkyl substances in indoor environments
Abstract Per- and polyfluoroalkyl substances (PFAS) include a wide range of halogenated chemicals, which have been used as water- and stain-resistant coatings for consumer products and industrial purposes. PFAS are persistent in the environment and several are bioaccumulative, and thus relevant for human and environmental health. Given their pervasiveness, we need to understand how we […]

Fluoridation of a lizard bone embedded in Dominican amber suggests open-system behavior
*Read original study online at http://fluoridealert.org/wp-content/uploads/barthel-2020.pdf Introduction Fossil bones represent valuable paleontological archives for reconstructing the paleobiology and -environments of vertebrates throughout geological time and thus also represent an important window into the evolution of life on Earth. The preservation of organisms or parts of them over long geological timescales requires exceptional conditions before and […]

Removal of fluoride from fertilizer industry effluent using carbon nanotubes stabilized in chitosan sponge
Highlights All assays were performed using gas scrubber effluent from the production of fertilizer industry. Carbon nanotube was anchored onto chitosan sponge and used like adsorbent. The adsorption capacity for fluoride reach around 975.4?mg?g?1 in kinetic assays. Reuse and regeneration were investigated and 5 cycles were obtained. The adsorption capacity kept similar values in all […]

Effects of fluoride content on structure and properties of steel slag glass-ceramics
Highlights Fluoride affected the type of crystal phase and crystallization process. Fluoride contributed to the formation of the Si–O bridge oxygen bonds. Fluoride had abnormal effect in high alkalinity glass. The glass-ceramics with flexural strength of 177.76 MPa can be obtained. Abstract The hot steel slag were utilized for preparing the glass-ceramics by melting method […]

Thermal behaviors of fluoride during (co-)incinerations of spent potlining and red mud: Transformation, retention, leaching and thermodynamic modeling analyses
Highlights Inorganic fluoride behaviors of spent potlining co-incineration were quantified. Addition of red mud positively affected fluoride transformations. . 30% red mud reduced fluoride leaching rate and enhanced retention rate of bottom ash. 66.01% of the total fluoride of the bottom ash was found to be insoluble fluorine. SiO2 and Al2O3 positively affected NaF conversion […]

Determination of fluoride component in the multifunctional refining flux used for recycling aluminum scrap
Abstract In this paper, the optimum fluoride component in the multifunctional refining flux used for recycling aluminum scrap was determined. Theoretical analysis of solid fluxing shows that strong stripping ability of oxide layer on aluminum surface for the flux and appropriate interfacial tensions between Al melt / inclusion (o-M-I), flux / inclusion (o-F-I), and flux […]
