The compound was irreversibly oxidized at a pencil graphite electrode in one or two oxidation steps which are pH-dependent. Based on the voltammetric peak for the second oxidation process of TU in phosphate buffer at pH 12.0, a square-wave voltammetric method was proposed for the determination of the compound in the range 6.3-30 mu m, with a detection limit of 1.29 mu m. The applicability to direct assays of wastewaters was also tested.eninfo:eu-repo/semantics/openAccessCyclic VoltammetryPencil Graphite ElectrodeSquare-Wave VoltammetryThioureaWastewaterArticle301Q1Q14551WOS:000297460700008
