Description
Description
Packaged Powder Pillows reagents (2105569) for the determination of Free Chlorine from Hach. The reagents are hermetically sealed in foil sachets, which provides them with a long shelf life. The reagent is simply poured into the measuring cuvette along with the sample. The analysis is carried out visually, for example using a color disc or with a HACH LANGE photometer.
Application: For testing residual chlorine and chloramines in water, wastewater, estuary water and seawater.
Parameter: Chlorine, free.
Summary of method: Chlorine can be in water as free chlorine and as combined chlorine. Both forms can be in the same solution and can be determined together as total chlorine. Free chlorine is in a solution as hypochlorous acid or hypochlorite ion. Combined chlorine represents a combination of chlorine-containing compounds, including monochloramine, dichloramine, nitrogen trichloride and other chloro derivatives. The combined chlorine oxidizes iodide (I–) to iodine (I2). The iodine and free chlorine reacts with DPD (N,N-diethyl-pphenylenediamine) to form a red solution. The color intensity is proportional to the chlorine concentration. To determine the concentration of combined chlorine, complete a free chlorine test and a total chlorine test. Subtract the results of the free chlorine test from the total chlorine test to get the combined chlorine concentration. To increase the range of analysis for the DPD method for total and free chlorine, add more indicator in proportion to the sample volume. For example, add a larger powder pillow of DPD Chlorine Reagent to a 5-mL sample.
