In this paper we have demonstrated a 2-dimensional photonic crystal based biosensor with line defect which can detect different fluorides in water. Simulation and analysis has been done for calcium fluoride, cesium fluoride, potassium fluoride, lithium fluoride and ...
Statistical analysis of the fluoride concentrations in rain water samples as obtained by CE, IC and ISE indicated that there was no evidence for systematic differences between CE and ISE, whereas the fluoride concentrations obtained by IC were significantly higher. The observed differences are most ...

As groundwater quality is not regularly tested in many areas, it is often unknown if the water in a given well or spring contains harmful levels of fluoride. Here we present a state-of-the-art global fluoride hazard map based on machine learning and over 400,000 fluoride measurements (10%...
Fluoride contamination studies were carried out in the ground water of 18 blocks of Mandla district. Water samples were collected from different locations from deep and shallow aquifers. Analysis of the samples revealed that fluoride con... S Kessharwani,J Sharma 被引量: 0发表: 2013年 C. K....
The source of fluoride in the groundwater of the study area is mainly from geological occurrence (i.e. fluoridebearing minerals, viz. apatite and biotitic mica). Microscopic analysis of the rock samples showed 5-10% apatite and 20-25% biotite, but other fluoride-bearing minerals like ...
The anion-exchange separation of titanium, zirconium, niobium, tantalum, molybdenum and tungsten, with particular reference to the analysis of alloys A detailed study was made of the adsorption of titanium, zirconium, niobium, tantalum, molybdenum, and tungsten on the anion-exchange resin, De- Acid...
And while fluoride intake from water and air can be evaluated relatively easily, it is much harder to estimate how much a given population ingests from foodstuffs because of the wide variations in individual eating habits and in fluoride concentrations in foodstuffs. 问题...
