Method for detecting heavy metals in soil

The invention relates to the technical field of soil analysis and detection, and particularly discloses a method for detecting heavy metals in soil. The detection method comprises the following steps that after soil is collected, soaking treatment with absolute ethyl alcohol is firstly carried out, and then soaking treatment with an H2O2 solution is carried out; microwave digestion is conducted on the soil sample; after digestion is completed, the sample is brought into an atomization system by carrier gas to be atomized and enters a high-temperature plasma channel in an aerosol form to be fully evaporated, dissociated, atomized and ionized, converted charged ions enter a mass spectrometer through an ion collection system, and separation and qualitative and quantitative analysis are performed according to the mass-to-charge ratio of the ions. The soil detection method can detect 21 heavy metals in the soil, and is high in operability and wide in analysis range. 本申请涉及土壤分析检测的技术领域，具体公开了一种土壤中重金属的检测方法；其检测方法包括：采集土壤
