| Abstract: | The method—cold atom absorption spectrophotometry（NCG-1 cold vapor atomic absorption mercury analyzer）was discussed for measuring content of mercury in sodium hydroride as food additives.The relative standard deviation was 6.80%～7.79% and the maximum relative deviation was 17.7% in the linear range 1ng/ml~5ng/ml.The method is simple,its precision and accuracy can meet requirements. |
