| Abstract: | The graphite samples were decomposed with nitric acid,low-temperature roasting to remove inorganic carbon and organic carbon,the fixed carbon content in the samples were determined by high frequency IR-Absorption carbon/sulfur determinator,The method has been validated by National Standard Reference materials and the result is in agreement with certified value with precision of 0.71%RSD,the detection limit of method was 0.02%,The method is suitable for determining fixed carbon content of low grade graphite. |
