| Abstract: | It is more and more give emphasis to development and utilize the trace chemical element of coal in our country. The ICP- AES method determines thorium, vanadium of coal is study in this paper. After work to the instrument term, measurement step, reagent, add the mark experiments, contrasting experiment, the results showed that precision is 5%, adding mark recovery rate is 95%- 105% by this method of determining thorium, vanadium of coal and this method precision is high, the work period is shorter compare with the determining method of chemistry. |
