The emphasis was on defining the procedure for sample preparation. Materials and methods 2.1. Determination of fluoride in toothpaste using an ion-selective electrode. The two main fluoride based additives are sodium fluoride (NaF) and sodium monofluorophosphate (MFP). The goal of the present study was to investigate the applicability of the optimized potentiometric method by using ISE for rapid and accurate determination of total fluoride in toothpaste and mouthwash samples of different origin. 2. Ion-Selective Electrode Determination of Fluoride Ion I. Light and C.C. But all toothpastes, even prescription ones, will contain other ingredients that target oral health problems such as bad breath, tartar build up and sensitivity. Prescription strength toothpaste contains sodium fluoride at a concentration of over 1500ppm up to 5,000ppm. By quantitative 19 F-NMR, their contents in toothpaste were simultaneously determined. Background Reading: T.S. Truman S. Light ; and ; Carleton C. Cappuccino ; Cite this: J. Chem. Educ. Publication History. Instrumentation While, yes, Tom's Of Maine fluoride children's toothpaste is technically designed for children, many of its loyal customers are adults who wanted to find a go-to, non-mint toothpaste… fluoride determination that is rapid, easy to perform and simple to calibrate. Determination of fluoride content in toothpaste using spectrophotometry Susanti Pudji hastuti, devinta lestari and Yohanes Martono Department of Chemistry Faculty of Science and Mathematics Satya Wacana Christian University Salatiga - Indonesia abstract Background: Intake excessive fluoride in children’s teeth are generally marked with white and brown patches. Considers the theory behind the operation of the ion-selective electrode and its application to determine the fluoride in toothpaste. NMR detects the soluble fluoride content of toothpaste which is the most important parameter in determining its effectiveness to prevent tooth decay. The advantages associated with the coupling of the fluoride-selective electrode as sensor to an FIA system, enables this combination to be used in a reliable low cost, robust analyser for the determination of fluoride in toothpaste as well as in effluent streams, natural and borehole water samples. The maximum level of the fluoride … 1975, 52, 4, 247. The fluoride content contributes to the quality of toothpaste. In the case of the mouth wash and toothpaste, appropriate dilution equations are needed to obtain the actual per cent fluoride in the weighed sample. Introduction A. Ion-Selective Electrodes The amount of a specific ion contained in an aqueous solution can be determined by direct potentiometric measurement of the voltage of a galvanic cell such as shown below. The fluoride concentrations of those solutions are read from the standard curve. Cappuccino, "Determination of Fluoride in Toothpaste Using Publication Date (Print): April 1, 1975. This is a simple, fast, interference-free, and green analytical method for the determination of sodium fluoride and sodium monofluorophosphate in toothpaste.
