DROP TEST PHOSPHONATE EQUIVALENCE (PPM) ATMP (1.0); Na5ATMP(1.3); HEDP (0.9); K6HDTMP (1.2); DTPMP (1.45), Na5DTPMP (1.7)
COMPONENTS:
1 x 5051 Instruction
1 x 9198P Sample Tube, Graduated, 25 mL, plastic w/cap
and purple dot
1 x 9315 Test Paper, pH, 1.8-3.8
1 x R-0686P-C Sulfuric Acid N (purple cap), 2 oz, DB
1 x R-0697-C Thiosulfate N/10, 2 oz, DB
1 x R-0802P-I XO Indicator Powder, 10 g
1 x R-0803-C Phosphonate Titrating Solution, 2 oz, DB
1 x R-0805-C Fluoride Masking Agent, 2 oz, DB
NOTE: Iron can cause negative interference at a level greater
than 5 ppm.
Orthophosphate and polyphosphate can cause
positive interference at all levels.
NOTE: Run a blank using tap water. Normal blank
requires about 2 drops of R-0803 Phosphonate Titrating
Solution to reach endpoint.
1. Rinse and fill 25 mL sample tube (#9198P) to 25 mL
mark with water to be tested.
2. Add:
1 drop R-0697 Thiosulfate N/10
10 drops R-0805 Fluoride Masking Agent
1 level dipper R-0802P XO Indicator Powder
Swirl to mix.
3. Adjust pH between 2.6 and 3.0:
Add 1 drop R-0686P Sulfuric Acid N. Swirl to mix.
Dip test paper (#9315) into sample, in direction of
arrow, for 3 seconds, with all color zones immersed.
Match indicator zone (unnumbered square between 2.7
and 3.0 color standards) with color scale. Read printed
pH value. If necessary, continue adding R-0686P Sulfuric
Acid N dropwise, swirling and checking pH with a new test
paper after each drop, until a pH between 2.6 and 3.0 is
obtained. Sample should be yellow.
4. Add R-0803 Phosphonate Titrating Solution dropwise,
swirling and counting after each drop, until color changes
from yellow to purple-pink. Always hold bottle in
vertical position.
5. Subtract drops of R-0803 Phosphonate Titrating Solution in
blank from drops in sample (Step 4).
Multiply
by appropriate conversion factor (see CONVERSION FACTORS).
Record as parts per million (ppm) phosphonate.
CONVERSION FACTORS:
To express phosphonate as:
Multiply drops by:
Aminotri(methylenephosphonic
acid) (ATMP) 1.0
Aminotri(methylenephosphonic
acid), pentasodium salt
(Na5ATMP) 1.3
1-Hydroxyethylidene-1,
1-diphosphonic acid (HEDP) 0.9
Hexamethylenediaminetetra
(methylenephosphonic acid),
hexapotassium salt (K6HDTMP) 1.2
Diethylenetriaminepenta
(methylenephosphonic acid)
(DTPMP) 1.45
Diethylenetriaminepenta
(methylenephosphonic acid),
pentasodium salt (Na5DTPMP) 1.7
