Extraction device for plants containing lead in soil surrounding heavy metal enterprises

Abstract

The invention discloses an extraction device for plants containing lead in soil surrounding heavy metal enterprises. The device comprises a device main body, a signal converter, an ion-selective electrode and an extrusion head, the surface of the device main body is provided with a display screen, the signal converter is arranged in the device main body, the top of the device main body is fixedlyconnected with an extraction assembly, the extraction assembly comprises a shell, a bottom plate, a metal column, a groove and flow guiding tubes, the ion-selective electrode is arranged at the bottomof the shell, sensitive membranes are symmetrically distributed on the top of the ion-selective electrode, the top of the shell is fixedly connected with a flip cover, and the extrusion head is arranged in the flip cover. The extraction device for plants containing lead in soil surrounding heavy metal enterprises can squeeze out essence in a plant sample by the arranged extraction assembly, and allows the essence to flow into the sensitive membranes along the groove, and the essence is detected to obtain accurate lead content data, so r subsequent phytoremediation is benefited, and the remediation efficiency is increased.

Description

technical field [0001] The invention relates to the technical field of lead control, in particular to a plant extraction device for lead in the soil around heavy metal enterprises. Background technique [0002] Lead is a viscous metal, which is easy to form stable substances with soil organic matter and iron-manganese oxides. The soil is widely distributed and has a strong accumulation capacity. It is mainly distributed in the soil layer above 20 cm, which has a great impact on vegetable planting. Human breathing and other ways into the human body, endangering human health. [0003] Most of the lead detection and treatment devices currently on the market are to extract the land and plant samples inside the land, and then test them. Only after knowing the lead content inside can the corresponding treatment be carried out. The operation process is cumbersome and requires a lot of time. It takes a long time, and at the same time, it is impossible to directly obtain lead-conta...

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a plant extraction device for lead in the surrounding soil of heavy metal enterprises, which solves the problem that most of the lead detection and control devices on the market extract the land and plant samples inside the land, and then It is tested to know the internal lead content before the corresponding treatment can be carried out. The operation process is cumbersome and takes a long time. At the same time, it is impossible to directly obtain the information of lead content in the polluted land environment. The limitations of the more troublesome problem
