  A simple, rapid, selective and highly sensitive spectrophotometric method is described for the quantitative determination of a tricyclic antidepressant drug, amitriptyline hydrochloride (AMT) in pure and in pharmaceutical preparations. The method is based on the bromination of AMT with known excess of bromine. The unreacted bromine is determined based on its ability to bleach the dye Eiochrome blue black R quantitatively at 530 nm. Beer’s law was obeyed over the concentration range 0.0–15 µg/mL. The molar absorptivity value was found to be 1.345×104 L/moL/cm, with the corresponding Sandell’s sensitivity values of 0.0233 µg/cm2. The limits of detection and (LOD) and quantification (LOQ) are also reported for the developed method. Intra- and inter-assay precision and accuracy of the method was establi.. Read More»
