摘要：
A spectrophotometric method of polyvinylpyrrolidone (PVPD) determination in waste water of pharmaceutical plants based on colored PVPD-organic dye adduct formation was elaborated. The optimal adduct conditions have been determined. The method was tested with waste water of a chemical pharmaceutical plant. The limit of determination 2.5 mg/l, relative standard deviation was less than 0.09.
