Abstract

The invention discloses a pesticide detection device, which comprises an electrode test paper, a detector, a micro controller and a servo computer. The electrode test paper is provided with an electrochemical reaction zone and a spectral detection zone, which can be used to contain a liquid sample to be measured in fixed volume. The detector applies voltage on an electrochemical reaction zone, detects current, and scans and analyzes the scattering spectra, reflectance spectra and transmission spectra of the spectral detection zone; and then the detected current and spectrum scanning result are transmitted to the servo computer through the data through a transmission element; the servo computer conducts calculation and analysis through; and then the analyzed pesticide kind and pesticide concentration are transferred to the detector, and the results are displayed.

Description

technical field [0001] The invention relates to a pesticide detection device, in particular to a pesticide detection device which detects the type and concentration of the pesticide by simultaneously detecting the spectrum and the current value. Background technique [0002] In today's society, due to the improvement of consumers' awareness, the problem of pesticide residues in food safety and hygiene, especially in vegetables and fruits, has become the focus of attention. As for the hidden dangers of personal safety caused by it, countries around the world have stricter requirements on the safety inspection of agricultural products, and the exporting countries of agricultural products will be more important for the quality control of exported agricultural products. [0003] Traditional chemical pesticides can be divided into nine categories according to their chemical structure, namely organophosphorus agents, radical nitrogen and heterocyclic compounds, carbamate agents, s...
