Spectrophotometric Determination of Uranium Using 2-(2-Thiazolylazo)-p-Cresol (TAC) in the Presence of Surfactants
No presente trabalho apresenta-se um método seletivo e sensível para rápida determinação de urânio usando o 2-(2-Tiazolilazo)-p-Cresol (TAC). O TAC reage com o urânio(VI) em pH 6,5 formando um complexo estável por pelo menos 3 h. Brometo de N-cetil-N,N,N-trimetil amônio (CTAB) e triton X-100 foram usados para aumento da sensibilidade e solubilidade do sistema respectivamente. O método permite a...
متن کاملSolvent Extraction Spectrophotometric Determination of Vanadium Using Sodium Salt of 2-Mercapto-Pyridine-N-Oxide as a Reagent
A solvent-extraction spectrophotometric technique is proposed as a new method for determination of trace quantities of vanadium. Sodium salt of 2-mercapto-pyridine-N-oxide (thione) forms a complex with vanadium instantaneously. The purple 1:2 complex is formed of pH 2.3, easily extracted in chloroform and shows strong absorbance at 500 nm. The extracted complex is found to obey Beer's law i...
متن کاملSelective and Validated SpectrophotometricMethods for Determination of Acyclovir and Ganciclovirwith 2, 4 as Reagent
New, simple and sensitive spectrophotometric methods for the determination of acyclovir and ganciclovirhave been developed. The method is based on the oxidation of 2, 4-dinitrophenyl hydrazine (2, 4 DNP) and coupling of the oxidized product with acyclovir and ganciclovirto give intensely coloredchromogen. Acyclovir and ganciclovirshowed maximum absorbance at 414 nm and 450 nm with linearity was...
متن کاملSimultaneolls spectrophotometric determination of molybdenum ( VI ) and titanium ( IV ) using 2 , 4 - dihydroxybenzaldehyde isonicotinoyl hydrazone
Determination of molybdenum(VI) by direct spectrophotometry and simultaneous determination of molybdenum(VI) and titanium(IV) are reported. Molybdenum(VI) gives a golden yellow colour with 2,4dihydroxybenzaldehyde isonicotinoyl hydrazone with a 1:2 metal-reagent stoichiometry at pH 1.5. The complex shows an absorption maximum at 445 nm with molar absorptivity and Sandell's sensitivity of 1.02x1...
متن کاملSpectrophotometric determination of Drugs & Pharmaceuticals Using Cerium(IV) as oxidant and Amaranth dye as analytical reagent
Simple, sensitive and accurate methods for determination of four drugs viz., Ciprofloxacin, Pantoprazole Sodium Sesquihydrate, Atrovastatin Calcium and Rosuvastine Calcium have been developed. The methods depend upon the oxidation of the drug by a known excess Ceric Ammonium Sulphate in sulphuric acid medium and subsequent determination of unreacted Ce (IV) using Amaranth dye. The methods have ...
