| Abstract: | Objective: To find out a new method for determining the contents of Vitamin K, solution. Methods: If the electric peak and concentration of Vt K1 range from 7.21×10-7g ml-1 to 8. 11 ×10-6g ml, it appeared the good linear relationship and the limit of the determination was 7. 8×10-8g ml. Results: If the electric peak and concentration of Vt K1, range from 7. 21×10-7g ml-1 to 8. 11×10-6g ml, it appeared the good linear relationship and the limit of the dectermination was 7. 8×10-8 g ml. Conclusion: Compared with the other method, it is simple rapid and easy to operate, and the satisfactory result can be obtained. |
