Problems solved by technology

[0004] At present, there are mainly chemical analysis methods for the determination of aniline. Chemiluminescence analysis has backward detection methods and poor detection results. A series of compounds with aniline groups can emit light or develop color, so this method has poor specificity and is difficult to accurately detect. To the specific content of aniline, the test results need to be further verified

Embodiment Construction

[0041] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention.

[0042] refer to figure 1 A method for detecting aniline in soil is used to detect the content of aniline in target soil, and mainly includes the following steps:

[0043] S1: collecting soil samples;

[0044] a: Define the target soil range and divide it equally into equal areas;

[0045] b: Sampling the edge and center of the target soil, counting as edge samples and center samples;

[0046] c: In the remaining unsampled area, random sampling is performed, and it is counted as a random sample

[0047] S2: Pretreatment of the soil that performed the same operation separately on the edge sample, center sample and random sample;

[0048] d: Air-dry, grind and shake...

Abstract

The invention discloses a method for detecting aniline in soil. The method comprises the following steps: S1, collecting soil samples; S2, independently pretreating soil subjected to the same operation as an edge sample, a center sample and a random sample; S3, drawing an aniline standard curve; S4, detecting the pretreated soil samples; and S5, comparing the aniline concentrations of different soil samples. The method has the advantages of being high in efficiency, convenient to operate and accurate in result.

Description

technical field [0001] The invention relates to the technical field of soil detection, in particular to a method for detecting aniline in soil. Background technique [0002] Soil environment detection refers to determining the environmental quality (or pollution degree) and its change trend through the determination of representative values ​​of factors affecting soil environmental quality. What we usually call soil monitoring refers to soil environment monitoring, which generally includes point sampling, Technical content such as sample preparation, analysis method, result characterization, data statistics and quality evaluation. [0003] As an important organic chemical raw material, aniline is widely used in the production processes of rubber, printing and dyeing, pharmaceuticals, plastics, and pottery glazing. It is a carcinogenic substance and is a highly toxic organic pollutant. Aniline can cause acute poisoning or chronic poisoning to the human body, causing symptom...
