Development of Fluoride Sensors and commercially viable affordable de-fluoridation Technology

Fluoride (F) contamination is one of the major contributors to the world water crisis causing fluorosis affecting about 200 million people worldwide. It is reported that around 24 countries are severely affected by high F concentration in drinking water. Till now, the availability of defluorinated water at the community level in the rural areas is a major concern due to the involvement of high cost and complex treatment modalities. Why this problem could not be solved till date? Fluoride is a negative ion, and its certain concentration 1.5 mg/l is needed for our body. F concentration can have a negative impact on human health. In India, we are struggling with the high fluoride load in the water (0.2 ppm to 48 ppm). Also research showed its levels in the drinking water varies from well to well within 100 m range. There is no technology available in the market that can maintain the fluoride levels in the water.. Therefore, development of low-cost and highly sensitive detector for F - ion is required together with affordable De-fluoridation product . I will talk about detection of Fluoride ions through TiO 2 NPs-CQDs-chitosan based sensor .Further my talk covers the arts and science to develop the affordable and commercially viable de-fluoridation technology equipped with sensors for communities using nano-biotechnology approaches
