Abstract

The invention discloses a method for determining turpentine in soil. The method comprises the following steps of 1) preparing a calibration curve sample; (2) purging and trapping a calibration curve sample; (3) determining a calibration curve sample by a gas chromatography-mass spectrometry (GC-MS) method; 4) drawing a calibration curve; (5) adding a soil sample to be detected; (6) extracting a soil sample to be detected in the vortex oscillator; (7) purging and trapping the soil sample to be detected; (8) measuring the gas chromatography-mass spectrometry (GC-MS) of the soil sample to be measured; and (9), calcualting the result. according to the method for determining the turpentine in the soil, a purge and trap-gas chromatography-mass spectrometry method is adopted for determination, instrument parameters and a pretreatment method are deeply studied, all the parameters are set according to the characteristics of soil pollution and the characteristics of the turpentine, and the method is easy to operate, high in standard recovery rate, small in standard deviation, and can met the environmental monitoring requirement of turpentine in soil.

Description

technical field [0001] The invention relates to the determination of pollutants in soil, in particular to a method for determining turpentine in soil. Background technique [0002] Turpentine is an important chemical raw material, its main component is terpene (approximately 64% α-pinene and 33% β-pinene), turpentine is an excellent organic solvent, widely used in paint, Adhesives and other industries. Turpentine is volatile and is transferred to water and soil through environmental migration. At the same time, industrial production and accidental spillage will also pollute the soil environment. As a receptor for pollutants, soil has a certain ability to accumulate. This kind of persistent pollution is serious. Harm the ecological environment and human health. [0003] Due to the harmfulness of turpentine, in GB 3838-2002 "Environmental Quality Standards for Surface Water", the limit value of turpentine in drinking water sources is 20 μg / L, and the harm of turpentine in so...
