“… 82 Dehydroxylation of hydroxyapatite component of bone char due to charring at high temperatures greater 500 °C decreases adsorption capacity, especially for anion pollutants such as fluorine and phosphorus. 83 Recently, Azeem et al 28 published a detailed review outlining the key benefits of using bone waste to produce bone char as well as bone-derived biochar, utilizing them as low-cost and effective methods for excluding potentially toxic elements (such as As, Cd, Cr, Cu, Ni, Pb, Hg, Sb, Se, V, and Zn) from contaminated water and soils. It has also been shown that the adsorption capacity of bone char closely correlates with the characteristics of its pores for metallic or cationic pollutants.…”

“…It is necessary to have both an awareness of fluoride’s dispersion and a comprehensive grasp of its many probable sources and especially removal technologies for management to be effective. Various water and groundwater treatment technologies have been applied to remove fluoride from water sources, such as electrodialysis [ 7 , 8 ], membrane filtration [ 9 , 10 , 11 ], and adsorption processes [ 12 , 13 , 14 , 15 , 16 ]. Of these technologies, when applied in a local community, adsorption is considered an excellent choice for defluorination due to its low cost, ease of design and operation, and high level of effectiveness [ 17 ].…”

Fluoride concentrations in the groundwater continue to be a major cause for concern in Thailand, particularly in the country’s north and west. The process of removing fluoride through adsorption has captured the attention of the abundance of ore in the mining industry. For the purpose of this investigation, the utilization of the adsorbent pyrolusite, which is a manganese mineral largely composed of MnO2, was a major component. Lab-scale experiments were conducted to investigate the efficacy of original pyrolusite ore (PA-1) and acid-modification PA (PA-2) created as low-cost adsorption materials for fluoride removal. The results of the adsorption rate in both PAs showed a fast rate of adsorption within 60 min of reaching equilibrium. According to the results of the adsorption capacity (qe) tests, PA that had been treated with an acid solution (PA-2) had the capacity to contain more fluoride (qe = 0.58 mg/g) than the PA that had been used initially (PA-1) (qe = 0.11 mg/g). According to the findings of an isotherm, primary adsorption behavior is determined by the effect that surface components and chemical composition have on porous materials. This is the first current study that provides a comparison between pyrolusite from Thailand’s mining industry and basic modified pyrolusite regarding their ability to remove a fluoride contaminant in synthetic groundwater by an adsorption process. Such an approach will be able to be used in the future to protect the community from excessive fluoride concentrations in household and drinking water treatment technology.

“…When the solution pH is less than the pHpzc of the adsorbent, the surface of an adsorbent becomes positively charged attracting more fluoride ions but when the solution pH is more than the pHpzc of the adsorbent, its surface becomes negatively charged repulsing the fluoride ions. Therefore, defluoridation is low when the initial pH is close to or higher than the adsorbent pHpzc due to proton release (deprotonation) (Sawangjang et al, 2021).…”

While exposure to low fluoride is essential for stronger bones and teeth, exposure to high concentration (> 3 mg/L/day) leads to hyperostosis and osteoporosis. This research evaluated the role of fertilizer application on soil’s fluoride release, and assess the effectiveness of using seaweed (Eucheuma cottonnii) derived materials for remedial purposes. The soil characterization results in the study area, indicated the availability of diverse fluoride fractions and in different quantities in the soil such that; water-soluble (Ws-F) (39.5 ± 0.5 mg/kg), Exchangeable (Ex-F) (3.5 ± 0.5 mg/kg), bound to iron/manganese (Fe/Mn-F) (3.1 ± 1.0 mg/kg), and organic matter bound (Or-F) (9.1 ± 2.1 mg/kg) fluoride whereas the total fluoride (Tot-F) was 422 ± 52.9 mg/kg. The study further reports that the use of three studied fertilizers (diammonium phosphate (DAP), Urea, and farmyard manure) accelerates the bioavailability of fluoride in the soil by increasing Ws-F. These results deliver alerts to the plant health regulators suggesting proper management of the quality of fertilizers used for the enhancement of crop quality particularly those used in fluoride-contaminated agricultural soils. While fertilizer application accelerated the bioavailability of fluoride in the soil, soil amendment with dried seaweed (DSW) led to a decrement of Ws-F from 81.7 ± 3.1 mg/kg up to 28.5 mg/kg whereas the fermented seaweed (FSW) decreased Ws-F from 81.7 ± 3.1 mg/kg to 12 ± 1.3 mg/kg following 5 % (w/w) amendments. But unlike DSW and FSW, seaweed-derived biochar (SB) adsorbed fluoride at specific pH five (5) from 103.1 mg/kg to 91.2 ± 3.2 mg/kg whereas hydroxyapatite activated seaweed-biochar (HSB) exhibited defluoridation capabilities at varies pH (3 – 11) with a maximum Ws-F reduction from 103.1 mg/kg to 21.6 ± 2.1 mg/kg which is close to the recommended limit of 16.4 mg/kg. The DSW and FSW defluoridation was based on complexation reactions, alteration of soil properties, and increasing the soil-specific surface area, but SB and HSB defluoridation was through chemisorption. Therefore, seaweed-derived materials are capable of remediation of fluoride contaminated soils and the study recommends further investigation on fluoride uptake by crops in pot and field experiments post-amendment with seaweed derived materials.
