Abstract:
The electrochemical reduction behaviour of xylenol orange, XO, in aqueous medium was studied over a pH range of 2.3–9.6 at a hanging mercury drop electrode, HMDE, on the basis of cyclic voltammetric, and double-potential step chronoamperometric and chronocoulometric data. The experimental results indicate that in acid medium (pH 2.28) the reduction of XO proceeds via an ECEC, first-order mechanism giving a single two-electron diffusion-controlled cyclic voltammetric wave. It was concluded that the rate-determining step is the protonation of the protonated anion intermediate to the final produc

Abstract:
The potential to remove xylenol orange (XO) from aqueous solutions through adsorption on γ-cyclodextrin-grafted carboxymethyl cellulose (CCMC) was investigated in batch experiments. The effects of contact time, adsorption temperature and initial XO concentration were discussed. Results of batch experiments showed that CCMC exhibited some sorption capacities towards XO. It was found that isotherm fitted Languir and Freundlich models for the adsorption of XO on CCMC. On the basis of the Langmuir analysis, the maximum adsorption capacities were determined to be 29.9, 27.1, 21.9, 16.2 and 16.1 mg

At various pH values, the effects of surfactants of different types have been studied: catamine AB, oxy-phos B, synthanol ALM-10 on the spectrophotometric characteristics of scandium with xylenol orange (XO). For complexation of scandium with XO, the optimum pH range is 1.56–2.44, the introduction of catamine AB under these conditions does not significantly affect the spectrophotometric characteris-tics of the complexes. The bathochromic shift from 508 to 637 nm and an increase in the intensity of light absorption by almost three times in the XO – Sc system — katamine AB occurs at a pH of 6.15

Abstract This work presents a 2D Fricke dosimeter with xylenol orange (XO), gelatine matrix and addition of sorbitol. The dosimeter was irradiated with various monitor units ranging from 500 to 10000 MU (3.6-72 Gy). The addition of sorbitol significantly reduced the diffusion coefficient of Fe3+ ions and improved the mechanical properties of the gel, while the chemical stability of the dosimeter decreased.

Feline infectious peritonitis (FIP), a devastating disease with near-complete mortality, is caused by the feline coronavirus (FCoV) and affects domestic cats worldwide. Herein, we report the development of a reverse transcription loop-mediated isothermal amplification (RT-LAMP) assay incorporating xylenol orange (XO) as a visual indicator for FCoV detection. The assay employed six oligonucleotide primers targeting regions of the nucleocapsid (N) gene. Under optimized conditions (65 °C, 60 min), amplification products were detected through pH-dependent colour changes in the XO dye. The RT-LAMP-

Abstract:
Magnetic quaternary chitosan salt CS/EPTAC/Fe3O4 was used for the removal of acid red 1 (AR1), xylenol orange (XO) and alizarin red (AR) in single, binary and ternary systems. In the single system, the maximal adsorption capacity was 781.55 for AR1, 537.40 for XO and 992.61 mg g−1 for AR at pH 3.0 and 25 °C. The adsorption kinetics of the three dyes followed the pseudo-second-order model. In the multicomponent system, preferential adsorption was observed for AR at low adsorbent quantities due to the small size of the molecule. When the adsorbent amount was greater, AR1 was adsorbed first becau

This paper presents the results of research on the Fricke–XO–Pluronic F–127 dosimeter. It consists of a Fricke dosimetric solution and xylenol orange (XO), which are embedded in a matrix of poly(ethylene oxide)-block-poly(propylene oxide)-block-poly(ethylene oxide) (Pluronic F–127). Upon irradiation, Fe+2 ions transform into Fe+3, forming a colored complex with XO ([XO-Fe]+3). The color intensity is related to the dose absorbed. The optimal composition, storage conditions, and radiation-induced performance of the Fricke–XO–Pluronic F–127 dosimeter were investigated. The optimal composition was
