Dicalcium phosphate dihydrate (DCPD) reacts with fluoride ion in an aqueous solution and forms stable fluoroapatite (FAp). This reaction requires a lag time to form nano-sized precursor, hydroxyapatite (HAp)-like calcium phosphate, on DCPD surface. This long lag time prevents DCPD from applying as an effective fluoride removal agent from waste water. The purpose of this study is to improve the ...

Fluoride is recognized as an effective agent for dental caries prevention. Generally, the main source of fluoride intake is drinking water. In this study, fluoride content in 18 commercial brands of bottled waters was investigated. Six samples from each batch of 18 Iranian commercial brands of bottled waters were supplied. The fluoride content of samples was analyzed by Fluoride Ion Selective E...

The water available for daily consumption may be contaminated by natural sources or by industrial effluents. One such a contaminant is fluoride. Exposure to fluoride in drinking water has a number of adverse effects on human health. One of the naturally available alternatives for defluoridation of water is Moringa Oleifera. Using colourimetric method, tests were conducted to get optimal values ...

Objectives One of the economical ways of dental caries prevention is using fluoride containing toothpastes. For fluoride to be effective in toothpastes, significant amount of fluoride need to be in solution form. Global standard of fluoride content of toothpastes is 1500 ppm (part per million).This study aimed to determine fluoride content of some special toothpastes. Methods This research was...

A polymer inclusion membrane (PIM) containing commercial ionic liquid methyltrioctylammonium chloride (Aliquat 336) as a carrier and cellulose triacetate (CTA) base has been used for the first time to remove fluoride from natural waters. Due anion-exchange characteristics of carrier, 1 M NaCl solution receiving phase. It found that addition tributyl phosphate (TBP) in formulation PIM increased ...

Background: Recently, concerns have been raised regarding the environmental and public health safety of azo dyes, most widely used synthetic dyes. The membrane technique has introduced as one efficient methods for dye removal treatments. Polyvinylidene fluoride (PVDF) manipulated by surfactants was studied dye, carmoisine. Methods: PVDF prepared via non-solvent-induced phase separation (NIPS) t...
