PROCEDURE 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 45 Hydrazine) from TESTING MENU. 4. Scroll to and select 45 Hydrazine from menu. 5. Rinse a clean tube (0290) with sample water. Fill to the 10 mL line with sample. 6. Insert tube into chamber, close lid and select SCAN BLANK. 7. Remove tube from colorimeter. Use the 1 mL pipet (0354) to add 4 mL of *Hydrazine Reagent A (4841). Cap and mix. 8. Use the 0.15 g spoon (0727) to add one measure of *Hydrazine Reagent B Powder (4842). Cap and shake vigorously for 10 seconds. Wait 2 minutes for maximum color development. An undissolved portion of Hydrazine Reagent B may remain in bottom of tube without adversely affecting results. 9. At the end of the 2 minute waiting period, mix, insert tube into chamber, close lid and select SCAN SAMPLE. Record result. 10. Press OFF button to turn 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 are obtained.

HYDROGEN PEROXIDE–LOW RANGE DPD METHOD CODE 3662-SC QUANTITY CONTENTS CODE 30 mL *Hydrogen Peroxide Reagent #1 *6452-G 100 *Hydrogen Peroxide LR Tablets *6454-J 1 Tablet Crusher 0175 *WARNING: Reagents marked with an * are considered hazardous substances.

Hydrogen peroxide, H2O2, is a colorless compound that is widely used as a bleaching or decolorizing agent in the manufacture of many commercial products. As an oxidizing compound it is also used in the treatment of sewage to reduce odors and corrosion due to hydrogen sulfide. It may also be used as a sanitizing agent for water treatment. Hydrogen peroxide is relatively unstable, and for this reason it dissipates quickly and leaves no residuals. APPLICATION: Drinking and surface waters; domestic and industrial waste water. RANGE: 0.00–1.50 ppm Hydrogen Peroxide METHOD: Hydrogen peroxide reacts with an excess of potassium iodide through the action of a catalyst and buffer to release an equivalent amount of iodine. The iodine in turn reacts with diethyl-p-phenylenediamine (DPD) to produce a pink-red SAMPLE HANDLING & PRESERVATION: color in proportion to the iodine released. Hydrogen peroxide is not stable in aqueous solutions. Exposure to sunlight and agitation will accelerate the reduction of hydrogen peroxide in dilute solutions. For best results start analysis immediately after sampling. INTERFERENCES: The likelihood of other oxidizing compounds interfering with this method is eliminated by the presence of hydrogen peroxide. Manganese may interfere and should be removed before analysis Smart2 TEST PROCEDURES 2.04 Hydrogen Peroxide–LR 1/2
