Abstract: The properties of thiourea dioxide(TD)in solution were studied by potentiomet-ric method.By analyzing the potential-time curves of various TD solutions with different pH and temperature,it was found that the pH value and temperature deeply affect the structure, reducing power and stability of TD solutions.TD is very stable in neutral solutions at room temperature.With the increase of basicity and temperature,the concentration of the tau-tomer B and the reducing power of TD solutions were enhanced,while the stability of TD decreased.

Key words: thiourea dioxide, property, potentiometry
