Spectrophotometric Determination of Chromium in Various Environmental Samples Using P-dimethyl Amino Benzyl Ethylene Diamine K.kiran*
A novel, simple p-dimethyl amino benzyl ethylene diamine reagent has been synthesized under ordinary laboratory conditions and this reagent was successfully applied for the determination of Chromium (VI) in various environmental samples. This reagent yields a red colored complex with chromium metal solution in sodium acetate-acetic acid buffer of pH 7.0. Maximum absorption was obtained at 560 n...
متن کاملSpectrophotometric Determination of Pantoprazole Sodium in Pharmaceuticals Using N-Bromosuccinimide, Methyl Orange and Indigo Carmine as Reagents
Two sensitive spectrophotometric methods are presented for the assay of pantoprazole sodium sesqui hydrate (PNT) in bulk drug and in formulations using N-bromosuccinimide (NBS) and two dyes, methyl orange and indigo carmine, as reagents. The methods involve the addition of a known excess of NBS to PNT in acid medium, followed by determination of unreacted oxidant by reacting with a fixed a...
متن کاملSensitive and spectrophotometric methods for the determination of Azathioprine in tablets using indigo carmine and methyl orange
A simple, economical, precise and fast visible spectrophotometric method has been developed for the determination of Azathioprine in tablet dosage form. Developed method is based on the formation of extractable colored complex of drug with colouring agent Indigo Carmine and Methyl orange. A wavelength maximum was found to be 683.7 nm and 566 nm. The concentration range of 15-50 μg mL-1 with of ...
