Technical field
The utility model relates to technical field of analytical instruments, relates in particular to the quick oxidation unit of a kind of ammonia nitrogen.
Background technology
Gas-phase molecular absorption spectrometry method (hereinafter to be referred as GPMAS) is based on gas that tested one-tenth branch resolves into and the relation of the absorption intensity of light and measured component concentration is observed this principle of law of Beer carries out quantitative measurement; According to the difference of absorbing wavelength, also can confirm tested composition and carry out qualitative analysis.Gas phase molecular absorption spectrometer is based on the GPMAS principle; Through chemical reaction the composition to be measured in the liquid phase sample is converted into gas; Make gas from liquid phase sample, separate and be written into the content that measuring system is measured gas, calculate the equipment of constituent concentration to be measured in the sample at last.It is used to measure ammonia nitrogen, sulfide, kjeldahl nitrogen, total nitrogen, nitrate, nitrite, sulphite, chlorion, permanganate index.
When utilizing gas phase molecular absorption spectrometer to measure the ammonia nitrogen index; (nitrite nitrogen is the further oxidation of itrogenous organic substance in the water body need ammonia nitrogen to be oxidized to nitrite nitrogen through the hypobromite oxygenant; Intermediate product in the changing into nitrate process), just can measure then.According to the environmental standard method HJ/T 195-2005 of national environmental protection portion of the People's Republic of China (PRC) (the 3rd page of the 2nd row) record, the ammonia nitrogen water sample need could measured behind the room temperature oxidation 20min more than 18 ℃ after adding the hypobromite oxygenant.If run into microthermal climate, environment temperature just must be used the water bath with thermostatic control auxiliary heating during less than 18 ℃.Therefore the ammonia nitrogen method for oxidation of describing in this standard is not only consuming time very long, and complex operation step, and work efficiency is low.There is not the record of special-purpose ammonia nitrogen oxidation unit in the document of being correlated with in addition, yet.
The utility model content
To existing the problems referred to above, the purpose of the utility model provides the quick oxidation unit of a kind of ammonia nitrogen convenient to operation.
It is that it comprises that the utility model solves the technical scheme that its technical matters adopted:
One ammonia nitrogen solution is carried arm;
One oxygenant is carried arm;
One carries arm and said oxygenant to carry arm to communicate with said ammonia nitrogen solution respectively and is used to export the container of nitrite reactant;
Said ammonia nitrogen solution carries the arm output terminal to be provided with a well heater.
Further, said well heater is water-bath heater, oil bath heater or electric heater.
The effect of this patent is: the oxidation unit of the utility model is simple in structure, and flexible operation, and can be easily and other analytical instrument coupling realizes that gas phase molecular absorption spectrometer mensuration, colorimetric estimation and other detect etc.
