A spore-based portable kit for on-site detection of fluoride ions
Highlights A spore-based portable kit was fabricated for visual and point-of-care testing of F–. The F– detection kit was successfully applied in surface waters and groundwater. The kit showed rapid, low-cost, eco-friendly, and ease of operation and storage. F– binding at near to the T2 Cu inhibited the reduction of O2 in CotA-laccase. Abstract The […]

Evaluation of straw ash as a cost-effective adsorbent for the removal of phosphate and fluoride from aqueous solution
Abstract In the present study, the straw ash (SA) was proposed to remove phosphate and fluoride from aqueous solution. The effects of SA dosage, initial contaminants concentration and initial pH on removal efficiency, adsorption kinetics and isotherms were investigated in batch experiments. The removal mechanisms were also discussed. The results show that solution pH was […]

Adsorptive removal of fluoride using biochar – a potential application in drinking water treatment
Highlights Elevated fluoride levels in drinking water root cause of dental and skeletal fluorosis. The Defluoridation capacity using water melon rind biochar(WMRBC was 9.5 mg/g. Anions such as Cl–, NO3–, SO42, HCO3–and CO32-did not affect fluoride adsorption. Abstract Fluoride as a geogenic contaminant is commonly encountered in groundwater-based drinking water sources. In the present study […]

Evaluation and DFT analysis of 3D porous rhombohedral Fe-modified MgO for removing fluoride efficiently
Highlights Calcination of Fe-modified MgO (CMF) was investigated for fluoride treatment. Electrostatic attraction, ion exchange, and hydrogen bonding are adsorption mechanisms. Fluoride was adsorbed at a low concentration (10 mg/L) with 95.2% removal rate. Theoretical adsorption capacity was 126.79 mg/g. DFT results explain the bonding mode of fluoride and the adsorbent. Abstract Three-dimensional porous rhombohedral […]

Comprehensive and critical appraisal of plant-based defluoridation from environmental matrices
Highlights State of the art presented on the use of various bioadsorbents and plants in defluoridation. Effect of parameters such as pH, temperature and kinetics is discussed. Overview of F– adsorption mechanisms, thermodynamic studies and uptake mechanisms. Exploration and selection of low-cost adsorbents and phytoremediators is required. Necessity of modification and commercialisation of specific adsorbents […]

Arsenic and fluoride contamination in groundwater: A review of global scenarios with special reference to India
The groundwater contamination with arsenic and fluoride has threatened the well-being of a vast number of people worldwide. Countries of South-East Asia, including Bangladesh, China, and India, are severely affected. In India, people residing in the middle and lower Gangetic planes and some Central and South-India areas characterized by hard rock terrain are worse affected […]

Novel aluminium (hydr) oxide-functionalized activated carbon derived from Raffia palm (Raphia hookeri) shells: Augmentation of its adsorptive properties for efficient fluoride uptake in aqueous media
Highlights RPSAC and ACRPSAC synthesized from Raffia palm shell biomass. ACPSAC had enhanced porosity and BET-surface area of 715.80 mg/g. Adsorptive removal performance of adsorbents for fluoride compared. Excellent fluoride adsorption capacity of 4.10 mg/g for ACRPSAC. Fluoride adsorption describes well with Langmuir model. Regeneration of ACRPSAC possible by recoating with Aluminium (hydr) oxide. Abstract […]
