On-line flow injection solid sample introduction, leaching and potentiometric determination of fluoride in phosphate rock.
A flow injection method with on-line solid sample dissolution was developed for the determination of fluoride in phosphate rock. The fluoride was selectively leached (98-102.4 % recovery) from a 50-mg powdered phosphate rock sample with 0.50 M citric acid. Using the zone sampling technique the fluoride in the buffered leachate was determined by injecting 87 muL into the carrier stream using a f...
متن کاملFlow injection potentiometric determination of Fe ( III ) using a fluoride - selective electrode as detector *
Flow injection analysis (FIA) system incorporating a fluoride ion-selective electrode (FISE) as detector is described. Laboratory-built cascade flow cell equipped with FISE and reference electrode is used for flow injection potentiometric determination of Fe(III) based on monitoring of the formation of FeF2 in acid solution. Under optimized flow conditions (4.0 mL min–1, 300 μL samples, 10–5 mo...
متن کاملPotentiometric Determination of Coextraction Constants
1 A theoretical treatment of potentiometric data is applied to calculate coextraction 2 constants (K IA) for three potassium salts from water into a liquid nitrobenzene phase. 3 The experiment involves treating nitrobenzene as a membrane and contacting it with 4 two aqueous solutions of different ion activities. In the presence of either a cation or 5 anion exchanger, the ratio of activities of...
متن کاملDetermination of Fluoride in the Bottled Drinking Waters in Iran
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...
