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 within 40...

Background: The compositions of Ferrous sulphate, Agarose and Xylenol orange dye (FAX) and Ferrous sulphate, Gelatin and Xylenol orange dye (FGX) in solution of distilled water and sulphuric acid are two tissue-equivalent gel dosimeters. Ionizing radiation causes oxidation of Fe ion to Fe ions which diffuse through the gel matrix and blur the image of absorbed dose over a period of hours after ...

Bulk single crystals of pure and xylenol orange dye (XO) admixtured L-Alanine Thiourea (LATU) were grown by slow evaporation technique. The cell parameters and crystallinity of pure and dye admixtured LATU crystals were confirmed by single crystal, powder X-ray diffraction and high resolution X-ray diffraction analyses. The functional groups present in the crystals were confirmed by FTIR analys...

Spectrophotometric measurements of the Fricke–gelatin–xylenol orange (FGX) gel dosimeter demonstrated reproducible linear dose response up to 25Gy. However, oxidation processes continue post-irradiation, affecting the response of this dosimetry system. Additional oxygenation during preparation increases the sensitivity of the gel but does not improve the auto-oxidation stability of the dosimete...

a simple, acurate and rapid spectrophotometric method for determination of sulphite thiamine hydrochloride (B1) is described. This used proton transfer reaction between ion with xylenol orange at pH(7.6) to develop red colour adduct that maximum absorption 580 nm. was by bleaching the product (xylenol orange-sulphite) optimum conditions established sulphite. Beer’s law obeyed in concentration r...

Lead forms the complexes with xylenol orange in the basic solution. An adsorptivedifferential pulse stripping method for the determination of lead is proposed. The procedureinvolves an adsorptive accumulation of lead on a hanging mercury drop electrode (HMDE) inthe presence of xylenol orange, followed by reduction of adsorbed lead by voltammetric scanusing differential pulse modulation. The opt...
