Embodiment Construction

[0020] The present invention will be described in detail below with reference to specific embodiments.

[0021] The invention provides a soil pollution detection method, which is specifically implemented according to the following steps:

[0022] Step 1, soil sampling: select the sampling area, arrange multiple sampling points, and the multiple sampling points are in the shape of regular hexagons; finally, perform sampling;

[0023] Step 2, drying the soil sample taken in step 1 to remove moisture, then adding acid, and then shaking and heating:

[0024] Put the soil sample taken in step 1 into an evaporating dish, and then heat it at 100-120° C. to remove water, and then add acid after removing water for vibration heating; wherein the acid adding process is adding nitric acid and phosphoric acid; wherein The mass fraction of nitric acid is 10% to 11%, and the mass fraction of phosphoric acid is 5% to 10%; the vibration heating process is to first shake the soil sample after ...

Abstract

The invention discloses a soil pollution detection method. The soil pollution detection method specifically comprises: the step 1, performing soil sampling; the step 2, drying the soil sample collected in the step 1 to remove moisture, adding acid, and oscillating and heating; and the step 3, detecting the soil sample treated in the step 2. According to the soil pollution detection method, the sampling points are hexagonal sampling points, the sampling points are rich, it is guaranteed that soil components in the test area are detected accurately, the steps are simple, the used raw materials are cheap and easy to obtain, and manpower and material resources are saved.

Description

technical field [0001] The invention belongs to the technical field of soil detection, and relates to a soil pollution detection method. Background technique [0002] Soil pollutants can be roughly divided into two categories: inorganic pollutants and organic pollutants. Inorganic pollutants mainly include acids, alkalis, heavy metals, salts, compounds of radioactive elements cesium and strontium, compounds containing arsenic, selenium, and fluorine. Organic pollutants mainly include organic pesticides, phenols, cyanide, petroleum, synthetic detergents, 3,4-benzopyrene, and harmful microorganisms brought by urban sewage, sludge and manure; If it exceeds the self-purification capacity of the soil, it will cause changes in the composition, structure and function of the soil, inhibit the activity of microorganisms, and gradually accumulate harmful substances or their decomposition products in the soil through "soil → plant → human body", or through "soil → plant → human body"....
