Simulation equipment for spectrophotometric determination of nitrate nitrogen in drinking water and use method of simulation equipment

Abstract

The invention discloses simulation equipment for spectrophotometric determination of nitrate nitrogen in drinking water and a use method of the simulation equipment, which relate to the technical field of water quality detection. The equipment comprises a photometer shell and a front shell, the front shell is fixed at the front end of the photometer shell, a sample rack, a translation mechanism, an ultrasonic vibration mechanism, a liquid adding mechanism and a sampling mechanism are arranged in the front shell, and a plurality of sample vessels are placed in a top groove of the sample rack; and the sample rack shuttles between the photometer shell and the front shell through the translation mechanism. Through the arrangement of the translation mechanism, the sampling mechanism and the liquid adding mechanism and the integrated design of liquid adding, sampling and measurement, liquid adding of the sample vessel is more convenient, data of all heights in a water area can be measured, ultrasonic assistance is carried out, the uniformity of a sample solution is more ideal, the measurement accuracy is improved, and the problems that existing nitrate nitrogen measuring equipment is single in function, inconvenient to use and not accurate enough in testing result are solved.

Description

technical field [0001] The invention belongs to the technical field of water quality detection, in particular to a simulation device for photometric determination of nitrate nitrogen in drinking water and a use method thereof. Background technique [0002] Nitrate nitrogen is the final product of the oxidation and decomposition of nitrogen-containing organic matter. Nitrogen in water exists in the form of nitrate, which is low or non-toxic. Excessive nitrate nitrogen content in water will cause harm to the human body. Or nitrite nitrogen polluted water will cause children's mental decline, slow response and other physical diseases. Nitrate can be converted into nitrite in the human body through the action of relevant enzymes in the body. Under the action of some nitrogen-containing organic compounds, it will The formation of chemically stable nitroso compounds can directly lead to canceration, deformity and mutation of human cells, thereby damaging the normal operation and h...

AI Technical Summary

Problems solved by technology

[0009] The purpose of the present invention is to provide drinking water nitrate nitrogen photometric measurement simulation equipment and its use method. By setting translation mechanism, sampling mechanism and liquid addition mechanism, the integrated design of liquid addition, sampling and measurement makes the liquid addition of sample dish It is more convenient, can measure the data of each height in the water area, and is assisted by ultrasound, which makes the uniformity of the sample solution more ideal, improves the accuracy of the measurement, and solves the problem that the existing nitrate nitrogen measurement equipment is single-function, inconvenient to use, and Inaccurate test results
