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
