[Abstract] Objective:Used neotype digestion device to digest marine products, then determined mercury.Methods: After microwave digestion , we determinate mercury in marine products by cold atomic absorption method.Results:The correlation coefficient was 0.999,RSDwas 3.6%, the average recovery rate of mercury was 85%-105%.Conclusion:The method performed good accuracy and precision. It’s a fast , simple and feasible method for analyzing marine products.
