SAMPLE HANDLING & PRESERVATION: Chlorine in aqueous solutions is not stable, and the chlorine content of samples or solutions, particularly weak solutions, will rapidly decrease. Exposure to sunlight or agitation will accelerate the reduction of chlorine present in such solutions. For best results, start analysis immediately after sampling. Samples to be analyzed for chlorine cannot be preserved or stored. INTERFERENCE: The only interfering substance likely to be encountered in water is oxidized manganese. The extent of this interference can be determined by treating a sample with sodium arsenite to destroy the chlorine present so that the degree of interference can be measured. Iodine and bromine can give a positive interference, but these are not normally present unless they have been added as sanitizers. Chlorine- Liquid DPD 2/3 Smart2 TEST PROCEDURES 2.04
PROCEDURE–FREE CHLORINE 1. Press and hold ON button until colorimeter turns on. 2. Press ENTER to start. 3. Press ENTER to select Testing Menu. 4. Select ALL TESTS (or another sequence containing 17 Cl DPD-Liq) from TESTING MENU. 5. Scroll to and select 17 Cl DPD-Liq from menu. 6. Rinse a tube (0290) with sample water. Fill to 10 mL with sample. 7. Insert the tube into chamber, close lid and select SCAN BLANK. 8. Remove the tube from colorimeter. 9. Add 5 drops of DPD 1A Free Chlorine Reagent (P-6740). 10. Add 5 drops of *DPD 1B Free Chlorine Reagent (P-6741). Cap and mix. 11. Insert tube into chamber, close lid and select SCAN SAMPLE. Record result as ppm free chlorine. PROCEDURE–TOTAL CHLORINE 12. Add 5 drops of *DPD 3 Total Chlorine Reagent (P-6741). Cap and mix. NOTE: For wastewater samples, Standard Methods for the Examination of Water and Wastewater recommends waiting 2 minutes for full color development. 13. Insert tube into chamber, close lid and select SCAN SAMPLE. Record result as ppm total chlorine. 14. SubtracttheFreeChlorinereadingfromtheTotalChlorinereadingto determine ppm combined chlorine. 15. Press OFF button to turn the colorimeter off or press EXIT button to exit to a previous menu or make another menu selection. NOTE: For best possible results, a reagent blank should be determined to account for any contribution to the test result by the reagent system. To determine the reagent blank, follow the above test procedure to scan a distilled or deionized water blank. Then follow the above procedure to perform the test on a distilled or deionized water sample. This test result is the reagent blank. Subtract the reagent blank from all subsequent test results of unknown samples. It is necessary to determine the reagent blank only when a new lot number of reagents is obtained.
