| Abstract: | Objective In order to establish a new atomic fluorescence method for rapid determination of trace arsenic and biological absorption ratio in lotus root, Methods With microwave assisted digestion samples, with close interpolation method for determination of arsenic in lotus root and soil. Results The results showed that the mass fraction of arsenic in the meat and joint of lotus root was small, while the mass fraction of arsenic in the skin and tip of lotus root was large. The biological absorption ratio of arsenic in each tissue was 79.54%-22.03%. Compared with the national standard method, there is no significant difference between the methods through the significance test, and the confidence of the conclusion is 95%. Conclusion The method does not need to draw standard curve and measure blank, it is quick, simple, simple to calculate, and has certain innovation and application value. |
