摘　　要：工业的快速发展对土壤结构等造成了一定的不良影响,导致生态环境污染日渐严重,影响着经济社会的发展和进步。根据研究调查显示,汞会以各种形态存在于自然界内,而对生态环境造成的影响也存在一定的差异性。因此,在实际发展的过程中,需要测定土壤以及沉积物中汞含量,进而针对实际情况制定解决方法。可以采用催化热解-冷原子吸收分光光度法进行测量,而这主要是因为其操作较为简单,步骤较少,分析消耗时间较短,且测定数据准确性更高,因此被大范围推广和应用。The rapid development of industries has had adverse effects on soil structure,leading to increasingly serious ecological environmental pollution,which affects the development and progress of the economy and society.Studies have shown that mercury exists in various forms in the natural environment,and its impact on the ecological environment varies.Therefore,it is necessary to measure the mercury content in soil and sediment and develop solutions based on the actual situation.Catalytic pyrolysis-cold atomic absorption spectrophotometry can be used for measurement,mainly because of its simple operation,fewer steps,shorter analysis time,and higher accuracy of measurement data.Therefore,it has been widely promoted and applied.
