Gabapentin is an anticonvulsant widely used in the treatment of epilepsy.An accurate and validated spectrophotometric method was developed as an alternative method to determine gabapentin in pharmaceutical products. This is a simple, accurate, precise, selective and visible spectrophotometric method. The method is based on the measurement of drug absorbance as a result of yellow solution format...

Background: Hydrogen peroxide (H2O2), produced by gamma ray irradiation to watery solution, was used as an analytical parameter for dosimetry of cobalt-60 (60Co) radiation. Materials and Methods: Detection of the produced H2O2 was carried out using two methods: an amperometric biosensor fabricated by immobilization of anthraquinone 2-carboxylic acid modified horseradish peroxidase on glassy car...

Acetophenone 2’,4’-dihydroxy semicarbazone (A24DHS) as a photometric reagent for the extractive spectrophotometric determination of Molybdenum (VI) is presented in this paper. The reagent A24DHS gave instantaneous and stable yellow colour with Molybdenum (VI) in the pH range 1.6 to 2.4. The system obeys Beer’s law in the concentration range of 1.0 μg/mL to 8.0 μg/mL at 370 nm. The Limit of Dete...
