Solid Phase Spectrophotometric Determination Of Cobalt By Xylenol Orange
A simple and sensitive solid phase spectrophotometric method for the determination of cobalt is proposed based on the reaction between cobalt and xylenol orange (XO). The reaction product is fixed on the anionic exchanger resin sephadex QAE A-25 at pH= 5. The optical absorbance of the anionic gel like resin, packed in a 1.00 mm cell is directly measured at 588.0 nm. The linear range of calibrat...
متن کاملSimultaneous spectrophotometric determination of lead, copper and nickel using xylenol orange by partial least squares
A partial least squares (PLS) calibration model was developed for the simultaneous spectrophotometricdetermination of Pb (ΙΙ), Cu (ΙΙ) and Ni (ΙΙ) using xylenol orange as a chromogenic reagent. The parameterscontrolling behavior of the system were investigated and optimum conditions were selected. The calibrationgraphs were linear in the ranges of 0.0–9.091, 0.0–2.719 and 0.0–2.381 ppm for lead...

متن کاملDetermination of trace amounts of thallium by adsorptive cathodic stripping voltammetry with xylenol orange.
Trace amounts of thallium(I) can be determined using adsorptive cathodic stripping voltammetry in the presence of Xylenol Orange (XO). The reduction current of the thallium(I)-XO complex ion was measured by square-wave cathodic stripping voltammetry. The peak potential was at -0.44 V vs. Ag/AgCl. The effect of various parameters (pH, ligand concentration, accumulation potential and collection t...
متن کاملSpectrophotometric determination of anionic surfactants in wastewater using acridine orange
A simple and rapid spectrophotometric method for the determination of sodium dodecyl sulphate (SDS), an anionic surfactant (AS) is developed. SDS forms a yellow coloured complex with acridine orange (ACO), a cationic dye. The complex is extracted in toluene. The absorbance of the complex in toluene layer is measured at maximum wavelength (λmax) of 467 nm. The calibration curve is linear in the ...
