| Abstract: | Incinerating temperature effects on assaying content of Cu, Mn, Fe and Zn heavy metal elements were reported in this paper by using porcelain crucible to incinerate fish samples such as carp and bream fish. The results indicated that it was feasible to use porcelain crucible to incinerate fish samples at a high temperature when heavy metal elements of Cu, Mn, Fe and Zn were assayed. The optimum incinerating temperatures were 450- 550, 450-550, 450-600, and 450-500℃, respectively. When the four heavy metal elements were determined at the same time, the optimum incinerating temperatures would be 450-500℃. The recovery rate of heavy metal elements was 97%-106% when incinerating temperature was 500℃. |
