Abstract

The invention belongs to the field of chemical detectors, and particularly relates to a nitrite detection board. The nitrite detection board comprises a board body and a cover body, wherein detectionholes sealed by the cover body are formed in the board body; nitrite gel detection layers are arranged inside the detection holes; the volume ratio of an aluminum oxide sol to a nitrite developer solution in each nitrite gel detection layer is 1:3 to 3:1; a plurality of detection holes are formed. The nitrite detection board is simple in structure, can be produced in batches, is low in reagent consumption, and achieves rapid environment-friendly detection of nitrite.

Description

technical field [0001] The invention belongs to the field of chemical detection equipment, and in particular relates to a nitrite detection board. Background technique [0002] Nitrite widely exists in the human living environment, especially in the water environment and food and other fields. Due to the potential toxicity of nitrite, its content determination has important practical significance in the fields of environmental science and public health. The determination methods of nitrite mainly include spectrophotometry, ion chromatography and electrochemical methods. Among them, the national standard analysis methods mostly use visible spectrophotometry and ion chromatography, and visible spectrophotometry is widely used in actual detection activities due to the low cost of equipment and relatively simple operation. [0003] The rapid detection of nitrite plays an important role in the on-site emergency monitoring of environmental emergencies, the general investigation ...
