Embodiment

[0054] Experimental objects: beans, eggplants and planting soil in a reclaimed water irrigation area. The soil and the beans and eggplants planted with different reclaimed water irrigation time were sampled and analyzed, and the nonylphenol was analyzed.

[0055] Experimental process: The soil samples were dried in a freeze dryer at -50°C for 12 hours, and 200g of dried soil was weighed and crushed with a high-speed pulverizer, passed through a 100-mesh sieve, and the sieved samples were collected for the next step; plant samples were dried in a drum at 65°C Dry in an air drying oven for 12 hours, weigh 50 g of dried plant samples, pulverize them with a high-speed pulverizer, pass through a 100-mesh sieve, and collect the sieved samples for use in the next step. Accurately weigh the sieved sample (soil sample 10.00g, plant sample 2.00g), add 0.1mg / kg diethyl phthalate-d4 as a substitute, stir and seal overnight, wrap it with filter paper and put it in The Soxhlet extractor was...

Abstract

The invention relates to a method for detecting trace nonylphenol (NP) in a soil sample or a plant sample, wherein the method includes the steps: 1) determining standard samples of nonylphenol and a substitute by GC-MS to calculate the relative response factor of nonylphenol and the substitute; 2) pretreating the soil sample and the plant sample; 3) adding the substitute with a certain concentration into the pretreated samples to be detected, and enriching nonylphenol and the substitute in the samples by Soxhlet extraction; 4) detecting the enriched soil and plant samples by GC-MS; and 5) calculating the concentration Cx of nonylphenol in the samples. The method has the advantages of simple pretreatment, low cost, low detection limit, high sensitivity and the like, and is suitable for sensitive and accurate qualitative and quantitative analysis of trace nonylphenol in bottom sediment, farmland and other soil samples and plant samples.

Description

technical field [0001] The present invention relates to the determination method of nonylphenol (Nonylphenol, NP) in soil and plant sample, more specifically relate to utilizing Soxhlet extraction and gas chromatography-mass spectrometry (GC-MS) to detect 12 kinds of traces in soil and plant sample Determination of nonylphenol. technical background [0002] Nonylphenol is a mixture of various isomers because it is prone to isomerization in the nonyl branch chain. Nonylphenol is a typical endocrine-disrupting substance, which has estrogenic effects, can interfere with the endocrine system of organisms, damage the nervous system and reproductive system, damage the antioxidant system, and damage DNA, thereby directly affecting the survival and reproduction of organisms. Strong toxicity and "three causes" effect. Due to its widespread existence, high toxicity and difficult degradation, it has been listed as a persistent toxic pollutant for priority control by the United Nation...
