摘要:

Derivative-Differential UV spectrophotometry and ratio-spectra first derivative spectrophotometry are presented for the simultaneous determination of analgesic and myorelaxan mixtures, namely acetaminophen (A)- phenprobamate (P). Derivative-Differential UV spectrophotometry is based on pH changes. The other method depends on the application ratio-spectra first derivative spectrophotometry to resolve the interference due to spectral overlapping.
