Abstract

The invention discloses a method and a device for quickly oxidizing ammonia nitrogen and relates to the technical field of analytical instruments. The invention aims at the problems that the conventional ammonia nitrogen oxidation method is time-consuming and complex in operation steps and does not have special ammonia nitrogen oxidation device. The method comprises the following steps: a, preheating ammonia nitrogen solution; and b, adding oxidant and oxidizing the ammonia nitrogen into nitrite nitrogen. The device comprises an ammonia nitrogen solution conveying branch pipe, an oxidant conveying branch pipe and a container, wherein the container is communicated with the ammonia nitrogen solution conveying branch pipe and the oxidant conveying branch pipe respectively and is used for outputting nitrite nitrogen reactant; and a heater is arranged at the output end of the ammonia nitrogen solution conveying branch pipe and is used for preheating the ammonia nitrogen solution. The method and the device is particularly suitable for measuring the ammonia nitrogen content by gas phase molecular spectroscopy and performing oxidation pretreatment on the ammonia nitrogen in the solution.

Description

technical field

[0001] The invention relates to the technical field of analytical instruments, in particular to a method for rapid oxidation of ammonia nitrogen and a device thereof. Background technique

[0002] Gas-phase molecular absorption spectrometry (hereinafter referred to as GPMAS) is based on the principle that the relationship between the light absorption intensity of the gas decomposed into the measured component and the concentration of the measured component complies with the principle of Beer’s law. , can also determine the measured components for qualitative analysis. The gas-phase molecular absorption spectrometer is based on the principle of GPMAS. It converts the components to be measured in the liquid phase sample into gases through chemical reactions, so that the gas is separated from the liquid phase samples and loaded into the measurement system to measure the content of the gas. A device for measuring the concentration of an ingredient. It is mainly...
