Residual Chlorine and Combined Chlorine.

USE OF THE OCTA-SLIDE VIEWER

The Octa-Slide Viewer should be held so
non-direct light enters through the back of the
comparator. With sample tube inserted at top,
slide the Octa-Slide bar through the viewer and
match with color standard.

EPA AC CEPTED PRO CE DURE

EPA accepted for NIPDWR monitoring. For compliance monitoring a
Check Standard should be prepared.

CHECK STAN DARD PREP A RA TION: 1 ppm Equiv a lent So lu tion

1. Dissolve 891 mg of potassium permanganate in 1000 mL of distilled
water in a volumetric flask (1000 ppm equivalent solution).

2. Dilute 1 mL of this solution to 1000 mL with distilled water in a
volumetric flask. This solution is equivalent to 1 ppm Free Available
Chlorine.

PRO CE DURE

FREE AVAIL ABLE CHLO RINE

1. Fill a test tube (0106) to the 5 mL line with sample water.

2. Add one *Chlorine #1R Tablet (6999A). Cap and mix until tablet

disintegrates. A pink to red color indicates the presence of Chlorine.

3. Insert test tube into the top of the Octa-Slide Viewer (1100). Slide
the 0.1 to 1.0 ppm Chlorine Octa-Slide Bar (3405) into the
Octa-Slide Viewer. Match sample color to a color standard. Record as
ppm Free Available Chlorine.

4. If the sample is darker than the 1.0 standard, remove 0.1 to 1.0
Octa-Slide Bar, replace it with the 1.0 to 6.0 Octa-Slide Bar (3404).
Match sample color to a color standard. Record as ppm Free
Available Chlorine.

NOTE: Save sample for Total Residual and Combined Chlorine
tests.

TO TAL RE SID UAL & COM BINED CHLO RINE

5. Add one *Chlorine DPD #3R Tablet (6905A) to the sample from
Step 4. Cap tube and mix until tablet disintegrates.

6. Insert test tube into the Octa-Slide Viewer (1100). Match sample
color to a color standard. Record as ppm Total Residual Chlorine.

7. Subtract Free Available Chlorine from Total Residual Chlorine.
Record as ppm Combined Chlorine.

Combined Chlorine =

Total Residual Chlorine – Free Available Chlorine

NOTE: Thoroughly clean and rinse test tubes after each test.
