| Abstract: | The method for determination of total mercury in the environmental water and soil samples by catalytic pyrolysis-AAS was established.The content of total mercury in the environmental water and soil samples was determined by DMA80 type direct mercury analyzer.The accuracy and precision were verified by the certificate reference materials.The results showed the good linearity as follows:lower concentration series were 0.01—0.3μg/mL,y=0.0116x+0.0012,R2=0.9997,higher concentration series were 0.50—4.00μg/mL,y=0.001x+0.0034,R2=0.9996,and RSDs were 1.1%—1.3%.The content of total mercury in the environmental water and soil samples was determined by catalytic pyrolysis-AAS.The mehtod is simple,rapid with good accuracy and sensitivity,and can be suit to determination of total mercury in environmental water and soil samples. |
