| Abstract: | Objective To investigate the advantages of nitric acid digestion method and its differences with the traditional method. Methods Ethanol was used to fully fix the testing sample. About 80-100 g of the testing samples were cut into pieces and digested with nitric acid. It was then centrifuged and washed to remove organic components. Smears were prepared and examined under the light microscope. Results The diatom had been identified with clear striations, counted conveniently and classified easily. Conclusion... |
