Fluoride

Inorganic Anions by Ion Chromatography (By EPA 300.0) 

Scope:

Part A of the test method covers the determination of common inorganic anions in drinking water, surface water, mixed domestic and industrial wastewaters, groundwater, reagent waters, solids (after extraction), leachates (when no acetic acid is used). Part B of the test method covers the determination of bromate, chlorate, and chlorite in drinking and reagent waters.

A small volume of sample, typically 50-100 uL, is introduced into an ion chromatograph. The anions of interest are separated and measured, using a system comprised of a guard column, separator column, suppressor device, and conductivity detector.

Fluoride

Inorganic Anions by Ion Selective Electrode (By SM 4500-F-C

Scope:

This method covers the determination of fluoride in drinking water. The fluoride electrode is an ion-selective sensor. The key element in the fluoride electrode is the laser-type doped lanthanum fluoride crystal across which a potential is established by fluoride solutions of different concentrtations. The crystal contacts the sample solution at one face and an internal reference soluton at the other. The fluoride electrode can be used with a standard calomel reference electrode and almost any modern pH meter having an expanded millivolt scale.

Fluoride

Inorganic Anions by Ion Chromatography (By EPA-RCA 9056A

Scope:

This method is applicable to the determination of chloride, fluoride, bromide, nitrate, phosphate, and sulfate in the collection solutions from the bomb combustion of solid waste samples, as well as all water samples.

A small volume (2-3 mL) of sample is injected into an ion chromatograph to flush and fill a constant volume sample loop. The sample is then injected into a stream of carbonate-bicarbonate eluent of the same strength as the sample. The samples are passed through three ion exchange columns (with different functionalities), and compounds are identified by retention time, and quantitated by peak height or area (by comparison with a standard calibration curve).
