| Abstract: | Method of determination rapidazol dye by visible ultraviolet spectrum is proposed. Fast blue VB salt is determined by an indirect way. It is transformed into rapidazol and determined as such, and the amount of fast blue VB salt is calculated from the result of rapidazol. The present method can be used as an effective industrial analytical method for the quality control in some printing and dyeing factory. |
