| Abstract: | The influence of temperature, pH value and Hg (Ⅱ ) on the directional reaction of thiourea dioxide with [Co( NH3)6]2+was studied. The reaction of thiourea dioxide with [Co( NH3)6]2+prefers to one-electron reaction. Simultaneously, two-electron reaction exits partially. The fraction of two-electron reaction of thiourea dioxide increases as raising temperature, pH value and adding Hg(Ⅱ ). The re-action mechanism of this system was also suggested. |
