CONCENTRATION OF HYDROGEN PEROXIDE
1.
Fill test tube (0715) to 10 mL line with sample water.
2. Add 10 drops of *Sulfuric Acid, 1:1 (6141WT). Swirl to mix. Make
sure solution is thoroughly mixed.
3. Add 1 drop of Ferroin Indicator (6410). Swirl to mix. Make sure
solution is thoroughly mixed. Solution will turn pale orange-pink if
hydrogen peroxide is present.
4. While gently swirling tube, add *Hydrogen Peroxide Titrant
(5650LWT) one drop at a time until pale orange-pink color changes
to colorless or pale yellow. Make sure solution is thoroughly mixed.
Count the number of drops added. Hold bottle vertically.
5. Discard titrated sample and rinse tube out with sample water.
6. Multiply the number of drops used in Step 4 by 50 (fifty). Record as
ppm Hydrogen Peroxide.
