Title
Standard Test Methods for Fluoride Ion in Water
ASTM International
Publication Date:
Jul 1, 2004
Scope:
These test methods(Footnote 2) cover the determination of fluoride ion
in water. The following two
test methods are given:
Test Method A covers the accurate measurement of total fluoride in
water through isolation of the
fluoride by distillation and subsequent measurement in the distillate
by use of the ion selective
electrode (ISE) method. The procedure covers the range from 0.1 to 2.6
mg/L of fluoride.
Test Method B covers the accurate measurement of simple fluoride ion
in water by means of an ion
selective electrode. With this test method, distillation is eliminated
because the electrode is not
affected by the interferences common to colorimetric procedures.
Concentrations of fluoride from
0.1 to 1000 mg/L may be measured.
This standard does not purport to address all of the safety concerns,
if any, associated with its
use. It is the responsibility of the user of this standard to
establish appropriate safety and
health practices and determine the applicability of regulatory
limitations prior to use. For a
specific precautionary statement, see 12.1.2.
Former Test Method A, SPADNS Photometric Procedure, was discontinued.
Refer to Appendix X1 for
historical information.
