TEST METHODS SPECIFICATIONS
INTRODUCTION
Fluoride may occur naturally in some ground waters or it may be added to public drinking water supplies to maintain a 1.0 mg/L concentration to prevent dental cavities. At higher concentrations, fluoride may produce an
objectionable discoloration of tooth enamel called Fluorosis, though levels up to 8 mg/L have not been found to be physiologically harmful.
APPLICATION
Drinking and surface waters; domestic and industrial waters.
RANGE
0.0 to 2.0 ppm Fluoride
METHOD
Colorimetric test based upon the reaction between Fluoride and zirconium dye lake. The Fluoride reacts with the dye lake, dissociating a portion of it into a colorless complex ion and dye. As the Fluoride concentration increases, the color produced becomes progressively lighter.
HANDLING & PRESERVATION
Samples may be stored and refrigerated in plastic containers.
INTERFERENCES
The following substances produce a positive interference at the concentration given:
Chloride (Cl-) |
7000 mg/L |
Phosphate (PO -3) |
16 mg/L |
4 |
|
Hexametaphosphate (NaPO3)6 |
1 mg/L |
The following substances produce a negative interference at the concentration given:
Alkalinity (CaCO3) |
5000 mg/L |
Aluminum (Al+3) |
0.1 mg/L |
Iron (Fe+3) |
10 mg/L |
Sulfate (SO -2) |
200 mg/L |
4 |
|
Color and turbidity must be removed or compensated for in the procedure. Temperature should be maintained within 5 degrees Celcius of room temperature.

Calibration
NOTE: Zeroing the meter with the sample water will result in an error. Meter must be zeroed with a reagent blank.
NOTE: The meter will remember the last scanned blank reading. It is not necessary to scan a blank each time the test is performed. To use the previous blank reading, instead of scanning a new one, scroll to Scan Sample and proceed. For the most accurate results, the meter should be blanked before each test and the same tube should be used for the blank and the reacted sample.
CALIBRATION
STANDARDS
The meter should be calibrated with fluoride standards. The calibration should be done with a distilled or deionized water blank and one fluoride standard of known concentration. The concentration of the calibration standard should be similar to the expected concentration of the sample that will be tested.
CALIBRATION PROCEDURE
1.Press and briefly hold 
to turn the meter on. The LaMotte logo screen will appear for about 3 seconds and the Main Menu will appear.
