General Knowledge of Dissolved Oxygen

 

Tips:Measuring Dissolved Oxygen by the Colorimetric Method

There are two variations of dissolved oxygen analysis by the colorimetric method. These are known as the indigo carmine method and the rhodazine D method. Both variations use colorimetric reagents that react and change color when reacted with oxygen in the water. These interactions are based on the oxidation of the reagent, and the extent of the color change is proportional to the dissolved oxygen concentration. Measuring dissolved oxygen by a colorimetric method can be done with a spectrophotometer, colorimeter, or a simple comparator. Using a spectrophotometer or a colorimeter produces more accurate results, while comparison against a comparator such as a color wheel or color block is quick and inexpensive. However, as the human eye is not objective, this can result in some inaccuracy.

 

Indigo Carmine

According to the indigo carmine method, the deeper the blue, the higher the dissolved oxygen concentration.

 

The indigo carmine method can be used for measuring dissolved oxygen concentrations between 0.2 and 15 ppm (mg/L). This method produces a blue color, the intensity of which is proportional to the dissolved oxygen concentration. Ferric iron, ferrous iron, nitrite, and sodium hydrosulfite can interfere with this method. In addition, reagents should be kept out of bright light as prolonged exposure can deteriorate the indigo carmine. However, this method is not affected by temperature, salinity, or dissolved gases. Low-range tests are time-dependent and should be analyzed within 30 seconds, while high-range tests require a two-minute processing time.

 

Rhodazine D

When measuring dissolved oxygen, the rhodazine D method will produce a rich rosy-pink color.

 

The rhodazine D method is used to determine very low dissolved oxygen concentrations. Able to measure in the parts per billion (ppb), rhodazine D reagents react with dissolved oxygen to form a deep rose-colored solution. This colorimetric method is not affected by salinity or dissolved gases such as sulfide that can be present in the water sample. However, oxidizing agents such as chlorine, ferric iron and cupric copper can interfere and cause higher DO readings. Other causes of error are polysulfides, hydroquinone/benzoquinone, and boron and hydrogen peroxide (if both are present). In addition, sample color and turbidity can affect the accuracy of the readings. This method is time-dependent, as the analysis must be made within 30 seconds of mixing the reagent.
