Coal Ash as a Low Cost Adsorbent for the Removal of Xylenol Orange from Aqueous Solution
The removal ofxylenol orange from aqueous solution onto the coal ash was investigated at room temperature. The results show that the adsorption capacity of xylenol orange increased as the adsorption time increased and then equilibrium established after 30 min adsorption time. The results obtained revealed that the coal ash removed about 80 % of xylenol orange from the aqueous solution withi...
متن کاملRemoval of Pb (II) Ion and Safranin Dye from Aqueous Solution by Sheep Wool
The ability of sheep wool to remove Pb(II) ions and safranin dye from aqueous solutions through the adsorption process was investigated at room temperature. The metal ions concentration was determined by flame atomic absorption spectrophotometer method. The influence of pH, contact time, amount of adsorbent, temperature and initial metal...
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...

15 صفحه اولMeasurement of lipid hydroperoxides by the ferric-xylenol orange method (1) characteristics of the ferric-xylenol orange/membrane phosphatidylcholine complex.
The ferric-xylenol orange (FOX) method for measurement of hydroperoxides is based on a technique that employs reduction of peroxides in an acidic condition by Fe2+ and formation of the colored ferric-xylenol orange (XO/Fe3+) product with a peak at 560 nm. The 560 nm absorbance peak of XO/Fe3+ shifts to a 610 nm peak with high absorption intensity in the presence of phosphatidylcholine. This is ...
