摘要
本研究立足农田土壤重金属污染土样标准,完善土壤采样条件,深入阐述微波消解-原子吸收光谱技术、土壤磁化率监测技术、电化学分析技术实际应用步骤,将重金属含量控制在400 mg/kg(铅元素PH≤7.5),2.0 mg/kg(汞元素)标准范围内,借助先进治理技术改善农田土壤质量,以期维护我国农业生产安全,加快农业现代化建设速度。
Based on the soil sample standard of heavy metal pollution in farmland soil,this paper improves the soil sampling conditions,and deeply elaborates the practical application steps of microwave digestion-atomic absorption spectroscopy,soil the heavy metal content is controlled within 400 mg/kg(lead PH≤7.5),2.0 mg/kg(mercury)standard range,and the quality of farmland soil is improved with the help of advanced treatment technology,in order to maintain the safety of agricultural production in China and accelerate the speed of agricultural modernization.
