Embodiment Construction

[0024] The technical scheme of the present invention is described in further detail below:

[0025] A soil heavy metal ion concentration automatic detection and restoration method, specifically comprising the following steps:

[0026] Step 1, preset normal heavy metal ion concentration threshold parameters;

[0027] Step 2, the electrochemical sensor is used to collect the voltage signal generated by the ion electrode, and then the membrane potential is obtained;

[0028] Step 3, the ion concentration can be obtained according to the actual value of the membrane potential, and at the same time displayed in real time through the display unit, specifically:

[0029] E M = E 0 + RT Z i F log a i

[0030] Where: where: E M is the membrane po...

Abstract

The invention discloses a method for automatic detection of concentration of heavy metal ions in soil and soil remediation. The method comprises the following steps: presetting a normal heavy metal ion concentration threshold value parameter; using an electrochemical transducer to acquire voltage signals generated by ion electrodes, and further obtaining membrane potential; according to the actual value of the membrane potential, obtaining the ion concentration, meanwhile displaying the ion concentration by a display unit, comparing the calculated ion concentration with the set normal heavy metal concentration threshold value, if the calculated ion concentration is higher than the normal concentration threshold value, giving an alarm by a control and alarm unit, and meanwhile starting an electric soil remediation device. The method disclosed by the invention can measure, display and store the ion concentration; the method charges current to the soil to enable the metal ions in the soil to be conveyed to the electrodes, and then intensively collects and processes the conveyed metal ions, so as to achieve the pollution control purpose.

Description

technical field [0001] The invention relates to an automatic detection method, in particular to a soil heavy metal ion concentration automatic detection and restoration method, which belongs to the field of automatic measurement. 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 detecti...
