Spectrophotometric Method for Determination of Chloramphenicol in Pharmaceutical Preparations using 1,2-Naphthoquinone-4- Sulphonate as a Chromogenic Reagent
A simple, sensitive and rapid spectrophotometric method for the determination of chloramphenicol in pure as well as in dosage form is described. The method is based on the condensation reaction of reduced chloramphenicol with sodium 1,2-naphthaquinone-4-sulfonate (NQS) in an alkaline medium to form an orange-red colored Schiff's base of maximum absorption peak (λmax) at 480 nm. Under the optimi...
متن کاملSpectrophotometric determination of osmium(VIII) in trace amounts using ethylene thiourea (ETU) as chromogenic reagent
A simple and highly sensitive spectrophotometric method has been described for the determination of trace amount of osmium(VIII) using ethylene thiourea (ETU) as a chromogenic reagent. The method is based on the formation of an instantaneous purple coloured complex at room temperature by the reaction of osmium(VIII) with ETU in strongly acidic (pH=1) solution having absorption maximum at 490 nm...
متن کاملRapid Spectrophotometric Determination of Trace Amounts of Chromium Using Variamine Blue as a Chromogenic Reagent
Um método espectrofotométrico simples, rápido e sensível foi desenvolvido para a determinação traço de cromo usando azul de Variamina como reagente cromogenico. O método proposto consiste na reação de cromo(VI) com iodeto de potássio, em meio ácido, liberando iodeto que então oxida o azul de Variamina formando um composto de cor violeta com o máximo de absorção em 556 nm. A lei de Beer é obedec...

متن کاملHighly selective first order derivative spectrophotometric determination of osmium(VIII) using anthranilic acid as a chromogenic reagent
A simple, selective and sensitive spectrophotometric method has been developed for the determination of osmium(VIII) using anthranilic acid as a reagent in the presence of Triton X-100. The molar absorptivity and Sandell’s sensitivity of the violet coloured species are 3.03 × 10 L mol cm and 3.5 ng cm respectively. Beer’s law is obeyed between 0.5-5.5 μg mL of Os(VIII) at 500 nm. The stoichiome...
