| Abstract: | + has a strong catalysis to the reaction between KBrO3 and methyl blue Oxide.The detendnation of trace V(5+)is on the basis of the catalytic dynamics condition.The testing limit is 4ng/L and the linear rang is 0 -200ng. The related error is 9% and the indexed recovery ratio is 90. 6% according to the finess and indexed recovery test of water samples. |
