| Abstract: | The best conditions for scperating concentrative trace iodine with V_2O_5 and Bi_2O_3 as flux and all the factors affecting the speed of catalysis reaction are researched. The sensitivity is raised and determination range of iodioe is extended bychanging temperature and time. The method has a very high sensitivity, good selection, simple operation, rapidity and economy. The lowest detect limit is 0.033 ppm and standard deviation is 4.45%. |
