Two simple, rapid, sensitive and accurate UVspectrophotometry (method I) and First order derivative (method II) have been developed for estimation of rabeprazole sodium in bulk and tablets. In (10% v/v) acetonitrile, the λmax of rabeprazole sodium was found to be 284 nm. The same spectrum was derivatised into first order derivative at Δλ = 2 and amplitude of the trough was recorded at 298 nm. I...

The rapid and continuous progress in trace analysis of metals is associated with development of several new techniques such as spectrophotometry. Thiosemicarbazones have been used as chromogenic reagents in spectrophotometric determination of metals. In this study the synthesis and characterization of pyridoxal thiosemicarbazone (PDT) and 2-acetyl pyridine thiosemicarbazone (2-APT) using IR, MS...

In this study, derivative UV spectrophotometric methods were developed for the analysis of diflunisal, which is used as a nonsteroidal anti-inflammatory drug. Analysis wavelengths of diflunisal for the first and second order derivative UV spectrophotometric methods were obtained as 235.6 nm and 228.8 nm, respectively. The linearity ranges were found as 1.0-25.0 μg mL-1 for the first order and 1...
