摘要：

A method for the determination of thiourea in acidic solution by titration with permanganate in the presence of a known amount of oxalic acid is described. The reaction is a four-equivalent oxidation of thiourea by permanganate. The oxalic acid in the solution effects a change in the mechanism such that thiourea becomes a four-electron reductant in its reaction with permanganate.
