Abstract
PURPOSE: To eanble measurement in high accuracy, by introducing NO2 - in waste water to the specific colored compound, adding defluorescent substance, and by measuring the concentration of colored compound concentration with resonant Raman method, without interference of colored ion for NO2 - concentration through the reduced resonant background by fluorescent.
CONSTITUTION: The sample waste water is filtered and suitable amount is picked up, and water is added, then sulfanilic acid colution is added, hydrochloric acid α- naphtylamine solution and acetic acid sodium colution are added to obtain pH 2.0W2.5, NaSCN as defluorescent substance is fed and well mixed, a part is filtered with millipore filter and enters the rotary cell to measure Raman spectrum. The intensity of RAman ray in wave number of 1250cm-1 produced with the radiation of argon ion laser, 488nm from the azo compound caused in equations I and II is measured, it is compared with dose obtained from the standard NaNO3 solution to detect the NO2 - concentration. From the concentration obtained, the NO3 - concentration existing at the same time can be obtained from the Raman ray intensity ratio of NO2 - and NO3 - simultaneously.
