Simultaneous Second Order Derivative Spectrophotometric Determination Of Gallium (III) and Aluminium(III) using Diacetylmonoxime IsonicotinoylHydrazone
Diacetylmonoxime Isonicotinoyl Hydrazone is new chromogenic reagent for the simultaneous determination of Gallium (III) and Aluminium(III). The reagent gives greenish yellow color in sodium acetateacetic acid buffer medium with the metal ions. The maximum absorbance at 377 and 367 nm for Ga(III) and Al(III) respectively. The molar absorptivities of Al(III) and Ga(III) are 2.69 x 10 and 3.17 x 1...
متن کاملEthyl Maltol as a New Ligand for Spectrophotometric Determination of Iron
In this study a new simple selective and sensitive spectrophotometric procedure for determination of Fe(III) is described. It is based on the formation of a colored complex between ferric iron and ethyl maltol, a strong and highly selective ligand for Fe(III). After mixing sample and reagent, and incubating at the room temperature, Fe(III)-ethyl maltol complex was extracted with different ...
متن کاملApplication of Classical Least Squares, Principal Component Regression and Partial Least Squares Methods for Simultaneous Spectrophotometric Determination of Rutin and Ascorbic Acid in Their Combined Dosage Form
This presented paper deals with application of three multivariate calibration methods methods for simultaneous spectrophotometric determination of two active substances in combined pharmaceutical formulation, composed of rutin (RU) and ascorbic acid (AA). The multivariate methods are classical least squares (CLS), principal component regression (PCR) and partial least squares (PLS). The results...
متن کاملSelective Separation and Preconcentration of trace Amounts of Gallium in Water and Rice Samples using Cloud Point Extraction and Determination by Inductively Coupled Plasma-Atomic Emission Spectrometry
In the present study a cloud-point extraction process using non-ionic surfactant Triton X-114 for selective extraction of gallium from aqueous solutions was developed. The method is based on the complex formation of Ga (III) with N, N′ -bis (salycilidene)-1, 2-phenylenediamine (salophen) as a chelating agent in buffer media of pH 5. After phase separation and dilution of the surfactant-rich pha...
متن کاملSimultaneous Spectrophotometric Determination of Vanadium(V) and Iron(III) in Micellar Medium by H-Point Standard Addition Method
H-Point Standard Addition Method (HPSAM) was applied for the simultaneous determination of V(V) and Fe(III). The method is based on the complex formation of V(V) and Fe(III) with chromazurol S (CAS) in acidic media and in the presence of cetyltrimethylammonium bromide (CTAB) as a micellizing agent. Acidic media and the presence of a micellar system improve selectivity and sensitivity. Fe (I...
