| Abstract: | It's a good way to use the semi-enclosed quartz-tube flame atomic absorbing method and add fixed amount matrix modifiers into standard solution and sample to measure the micro-mercury of the food. The operating of the method is very convenient and it's no necessary to use auxiliary equipments in applying the method. The rate of recovery of the method is 98. 6 % and the relative standard deviation is 1. 02%. |
