| Abstract: | A method for the determination of residual TMA in the bakelite-type macromolecule complex material has been established. The whole process includes sample pretreatment, TMA extraction and GC analysis. After the samples have been pretreated, the TMA in them was extracted at (38 +/- 2) degrees C for 16 hours. Then the content of TMA in the liquid can be determined directly. From the experimental results we can conclude that the whole method is cheap, simple and accurate. It meets the requirement of microanalysis and can be used to determine real samples. |
