| Abstract: |
| The absorption characteristics of the carbon blacks with different structures and their iodine absorption processes were analysed.The determination of the iodine absorption of carbon black specified in GB/T 3780.1一91 was discussed with the emphasis on the requirements of test temperature，standard solution concentration and sample amount.It is considered that GB/T 3780.1一91 is mainly applicable to the determination of iodine absorption of furnace carbon black which contains only few polar functional groups on its surface.The concentration of iodine solution(1/2I2) should be 0.O473mol·L-1 in order that the determined iodine absorption of carbon black is in accordance with the specific surface area of carbon black determined by BET absorption. |
