| Abstract: | Objective]To establish a new method for mercury determination in food by direct mercury analyzer.Methods]The mercury content in food was determined by thermal decomposition/amalgamation atomic absorption spectrophotometry.Results] The regression equation: A=0.043 0 Hg+0.016 0;correlation coefficient : R=0.999 5;the linear range was 0.00-10.00 ng;precision was 0.62%-17.2 %;recoveries were 85.8%-105.8%;detection limit was 0.03 ngHg.Conclusion]The method is simple,rapid.The indicators can meet the requirements of determination of mercury in food. |
