Biosorptive removal of fluoride from aqueous solution onto newly developed biosorbent from Ficus benghalensis leaf: Evaluation of equilibrium, kinetics, and thermodynamics
Abstract Need for developing an effective defluoridation method using locally available resources and recycling of agriculture waste is still encouraging the researchers for achieving sustainability. Greater attention was shown towards developing biosorbent for deflouridation utilisation of locally available plant biomass such as leaves. Present research envisages on developing a novel biosorbent from Ficus benghalensis leaf […]

Highly efficient removal of fluoride from aqueous media through polymer composite membranes
Highlights Aluminum and calcium based adsorbents were studied for defluorination. The effect of temperature, pH, reaction time and concentration were evaluated. Composite membranes for fluoride removal from aqueous solutions were prepared. Membrane filters showed suitable morphological and structural properties. Fluoride rejection rates around 70% were achieved. Abstract Different aluminum and calcium based particles, montmorillonite (MMT), […]

Electrodialysis for fluoride and nitrate removal from synthesized photovoltaic industry wastewater
Highlights Electrodialysis for the fluoride and nitrate removal from photovoltaic wastewater. Significant fluoride removals obtained in acidic or neutral medium after 6 min. Nitrate delays the fluoride removal from and makes the removal less effective. Abstract Fluoride and nitrate ions are the main pollutants in the photovoltaic cells manufacturing effluent. Their presence in the effluent […]

Low-mineral direct drinking water in school may retard height growth and increase dental caries in schoolchildren in China.
Highlights Children drunk low-mineral direct drinking water in school had lower height and height increases. Children drunk low-mineral direct drinking water in school had higher prevalence and incidence of hypoevolutism. Drinking low-mineral direct drinking water in school was positively associated with the incidence of hypoevolutism. Children drunk low-mineral direct drinking water in school had higher […]

Optimization of fluoride removal from aqueous solution using Jamun (Syzygium cumini) leaf ash
Highlights Adsorbent was prepared by calcination at 500 °C. Jamum leaf ash (JLA) rich in calcium and calcium minerals favoured F– adsorption. F– adsorption was a complex process involving both boundary layer effect and intraparticle diffusion. Adsorption process of fluoride by JLA was spontaneous, feasible and exothermic. Removal of fluoride was done by adsorbent prepared from […]

A review of emerging adsorbents and current demand for defluoridation of water: Bright future in water sustainability
Highlights Adsorption capacities and fluoride removal efficiencies have been presented for a wide range of adsorbents. Aluminium-based adsorbents are most effective but it’s leaching cause health problems. Langmuir isotherm and pseudo-second-order kinetic were found to be best fitting model. Current desorption strategies are inadequate and environmentally not sustainable. Reusability of an adsorbent is very important […]

Fluoride removal from groundwater by adsorption technology: the occurrence, adsorbent synthesis, regeneration and disposal
Abstract In the Eastern corridor of the Northern region of Ghana, the presence of high fluoride concentration in the groundwater has made many drilled boreholes unusable for drinking. Little is, however, known about the factors contributing to the occurrence of high fluoride in the groundwater. Fluoride-contaminated groundwater can be treated by adsorption, but is hampered […]

Bone char with antibacterial properties for fluoride removal: Preparation, characterization and water treatment.
Highlights New method for preparation of bone char with antibacterial character is reporting. Silver solutions were used in the modification of bone char. Concentration of silver was determinant in the antibacterial character of bone char. Bone chars with and without silver compounds were efficient in fluoride removal In the present work, it was established a […]

Defluoridation technology for drinking water and tea by green synthesized Fe3O4/Al2O3 nanoparticles coated polyurethane foams for rural communities
Abstract Fluoride (F) contaminated ground water poses a serious public health concern to rural population with unaffordable purification technologies. Therefore, development of a cost-effective, portable, environment and user-friendly defluoridation technique is imperative. In the present study, we report on the development of a green and cost-effective method that utilizes Fe3O4 and Al2O3 nanoparticles (NPs) that […]

Fluoride ions vs removal technologies: A study
Abstract Literature reported that drinking water is a precious and scarce resource and it has to be protected and kept free from any kind of contamination. Further, it has to be used carefully without wasting. Literature also reported that fluoride bearing rocks are abundant in India, as a result, fluoride leaches out and contaminates the […]
