原始语种摘要: The incidence of dental and skeletal fluorosis due to excessive ingestion of fluoride through drinking water is increasing alarmingly in various parts of the world. Though several defluoridization techniques having different principles of actions such as reverse osmosis, ion exchange and chemical treatments are available, none is found to be ideal due to cost effective, sludge transfer, maintenance of pH and demineralization after treatment and non-attainable for rural regions. Hence, the search for new methods to selectively remove fluoride from the drinking water sources still continues. Earlier, we have reported that treatment with raw vermiculite, a type of mica, at a mesh size of 80 significantly adsorbed the fluoride present in the water samples. Strychnos potatorum Linn., commonly...
