Abstract Ibuprofen, propionic acid derivative, was subjected to different temperature (20, 30, 37, 40, 50 and 60 ºC) and pH (3, 4, 5, 6, 7 and 8) conditions. The samples were assayed at time intervals 0, 12, 24, 36 and 48 h by taking their UV/VIS absorbance at wavelengths 272 and 258 nm. Ratios of absorbance at any time were taken as a parameter, proportional to the concentration of intact substance. The degradation processes were assumed to follow ...
