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 […]

Salinity enrichment, sources and its contribution to elevated groundwater arsenic and fluoride levels in Rachna Doab, Punjab Pakistan: Stable isotope approach as an evidence.

Highlights Salinity is due to ion exchange, mineral dissolution, and partial input of evaporation. Arsenic showed no clear relationship with salinity in groundwater of study area. Saline ground waters had relatively oxidizing conditions that restricted As enrichment. Groundwater salinity is one of the factors which influences the enrichment of F?. Abstract The present study aimed […]

Marysville water plant supervisor advocates for end of fluoride

The supervisor of Marysville’s water plants is advocating that the city abandon the use of fluoride, but officials haven’t formally responded after issues were raised this week. During a presentation Monday, Bari Wrubel, who oversees the water filtration and wastewater treatment plants, said city staff has been working in limbo after a leak in fluoride […]

British Fluoridation Society: plans and predictions in a post-COVID world

How important is fluoridation in a post-COVID world? The appeal of water fluoridation has never been greater. COVID-19 and the consequent imperative to avoid aerosol generating procedures (AGP) underscore how counter-intuitive it is to be treating disease when it could and should be prevented. COVID has informed us that we need to invest in public […]

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 […]

Christchurch candidate’s secret fluoridation claims ‘ludicrous’

Claims the Government has secretly fluoridated parts of Christchurch have been slammed as “ludicrous”. New Zealand Public Party Christchurch East candidate Glen McConnell said water supplied to east Christchurch had been secretly fluoridated for almost a decade. McConnell posted the claim on his Facebook page, which has 297 followers, on September 17. “…does East Christchurch […]

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 […]

Kentucky: Fluoride pro and con: Lawmakers hear the debate

Sen. Julie Raque Adams, R-Louisville, left, and Rep. Kimberly Poore Moser, R-Taylor Mill, testifying on potential legislation to give local governments control over tobacco marketing and sales. FRANKFORT, Ky. (WTVQ) –  Passionate advocates for and against adding fluoride to tap water testified Tuesday before lawmakers on the Interim Joint Committee on Local Government. For decades, […]

Fluoride pro and con: Lawmakers hear the debate

FRANKFORT, Ky. (WTVQ) –  Passionate advocates for and against adding fluoride to tap water testified Tuesday before lawmakers on the Interim Joint Committee on Local Government. For decades, the Centers for Disease Control and Prevention has recommended safe amounts of fluoride be added to tap water to prevent tooth decay. State regulations require water to […]
