Abstract

The invention discloses a heavy metal ion concentration automatic detection system. The system comprises a microcontroller module, an ion concentration detection unit, a voltage amplifier unit, an analog-digital converter unit, a display unit and a data storage unit, wherein the ion concentration detection unit, the voltage amplifier unit and the analog-digital converter unit are connected in sequence; the analog-digital converter unit, the display unit and the data storage unit are connected with corresponding ports of the microcontroller module. The system can perform computation processing according to voltage signals gathered by the ion concentration detection unit, so as to obtain the ion concentration, namely can obtain the corresponding relationship between the ion concentration and membrane potential according to a Nernst equation, further obtain the ion concentration by detecting the voltage signals, and can realize the measurement, display and storage of the ion concentration.

Description

technical field [0001] The invention relates to an automatic detection system, in particular to an automatic detection system for the concentration of heavy metal ions, which belongs to the field of automatic detection. Background technique [0002] With the continuous acceleration of industrialization and the continuous growth of population, heavy metal pollution such as lead, copper and zinc has become a global problem. The mining, smelting, processing and commercial manufacturing activities of heavy metals are increasing day by day. Sudden water quality heavy metal pollution accidents caused by accidental leakage and illegal discharge occur from time to time. Heavy metals are highly toxic, difficult to be metabolized in the environment, easy to be enriched by organisms and have biomagnification effects, etc., which will not only pollute the water environment, but also seriously threaten the survival of humans and aquatic organisms. Effective and accurate detection of heav...
