“…Many plants can absorb contaminants from the environment, including fluoride. The selection of tolerant and resistant species is essential for the success of phytoremediation (Weerasooriyagedara et al, 2020). The main conditions that influence fluoride absorption are solution pH, Fconcentration, chemical form of fluorine, plant species, and the presence of other elements, such as calcium, aluminum, and phosphorus (Baunthiyal & Ranghar, 2014;Singh et al, 2018).…”

A novel fluorenone derived Schiff base chemosensor (1) has been synthesized as a colorimetric sensor for fluoride (F À ) ions in CH 3 CN and characterized by various analytical techniques. The chemosensor 1 perceived high selectivity for F À ion detection in the presence of other anions along with naked eye color change from yellow to orange-red with quantitative detection limit of 900 nM. The UV-vis changes, density functional theoretical (DFT) calculations and 1 H NMR titration studies pointed to F À ion induced deprotonation of À OH of sensor 1 that has been proposed to be responsible for the observed absorption as well as color changes. The sensor 1 has also been efficiently applied for the solid state concentration dependent naked eye detection of F À ions in the form of filter paper strips and smartphone applications. The in-situ generated 1-F À complex was further utilized for cascade recognition of calcium gluconate (CG). The reversible and reproducible changes produced by the addition of F À ions and CG enabled 1 to be used as "INHIBIT" molecular logic system and "SET/RESET" memorized device at the molecular level.

“…Plant-based approaches to remediate fluoride from the environment have become an intense study area in recent years [213]. A number of plant-based systems have been investigated for fluoride remediation from contaminated water [213,[251][252][253]. Khandare et al [254] investigated four hydrophytes Canna indica, Epipremnum aureum, Cyperus alternifolius, and Cyperus rotundus.…”

Bioaccumulation of Fluoride in Plants and Its Microbially Assisted Remediation: A Review of Biological Processes and Technological Performance

et al. 2021

Fluoride is widely found in soil–water systems due to anthropogenic and geogenic activities that affect millions worldwide. Fluoride ingestion results in chronic and acute toxicity, including skeletal and dental fluorosis, neurological damage, and bone softening in humans. Therefore, this review paper summarizes biological processes for fluoride remediation, i.e., bioaccumulation in plants and microbially assisted systems. Bioremediation approaches for fluoride removal have recently gained prominence in removing fluoride ions. Plants are vulnerable to fluoride accumulation in soil, and their growth and development can be negatively affected, even with low fluoride content in the soil. The microbial bioremediation processes involve bioaccumulation, biotransformation, and biosorption. Bacterial, fungal, and algal biomass are ecologically efficient bioremediators. Most bioremediation techniques are laboratory-scale based on contaminated solutions; however, treatment of fluoride-contaminated wastewater at an industrial scale is yet to be investigated. Therefore, this review recommends the practical applicability and sustainability of microbial bioremediation of fluoride in different environments.
