Hanna HI3810 Offers

This chemical test kit measures dissolved oxygen using modified Winkler titration. It is supplied complete with everything needed to perform approximately 110 tests.

Features

  • All required materials are included with the test kit, such as the glass stoppered bottle, indicator and reagent bottles, and calibrated syringe
  • High resolution
  • Replacement reagents available, there is no need to buy a new kit when reagents are exhausted

Applications

The concentration of dissolved oxygen in water is extremely important in nature as well in man's environment. In oceans, lakes, rivers, and other surface water bodies, dissolved oxygen is essential to the growth and development of aquatic life. Without oxygen, water can become toxic due to the anaerobic decaying of organic matter. In man's environment, water must contain at least 2 mg/L of oxygen to protect water pipes from corrosion. However, boiler system water, in many cases, cannot contain greater than 10 mg/L oxygen. A modified Winkler method is used in the HI3810 test kit. Manganous ions react with oxygen in the presence of potassium hydroxide to form a manganese oxide precipitate (Step 1). An azide is present to prevent any nitrite ions from interfering with the test. With addition of acid, manganese oxide hydroxide oxidizes the iodide to iodine (Step 2). Since the amount of iodine generated is equivalent to the oxygen in the sample, the concentration of iodine is calculated by titration of thiosulfate ions that reduce the iodine back to iodide ions (Step 3).

  • Step 1: 2Mn2+ + O2 + 4OH- → 2MnO(OH)2
  • Step 2: MnO(OH)2 + 2I- + 4H+ → Mn2+ + I2 + 3H2O
  • Step 3: I2 + 2S2O32-- + S4O62-
