SYSTEM OVERVIEW
The direct concentration fluoride method by Ion Selective Electrode
(ISE) is more precise and accurate than the SPADNS method. The procedure
provides rapid, uncomplicated determinations, and eliminates
interferences associated with colorimetric methods.
Interferences from polyvalent cautions at the usual levels of a few
parts per million are removed by the use of either of the suggested
buffers. The electrode method has been approved by EPA, APHA and ASTM.
The measurement of fluoride in drinking water is an approved ASTM
method. Approval number ASTM D 1179.
