| Abstract: | Objective：To determine the content of Cd、Pb in sweet potato individually. Methods： Flame atomic absorption spectrometry was used. Results： The results show that the content of Cd of the 2-I2-8 was 0.1499 mg/kg,it was higher than others, the content of Pb of the Wanzi56 was 4.510 mg/kg , it was higher than others. New evidence was provided for food safety and breeding of sweet potato and control of environment pollution in this study. |
| Keywords: | atomic absorption spectrometry sweet potato heavy metal elements |
