The spectrophotometric determination of thorium with eriochrome black T
Mikrochimica Acta, 1961From 0.5 to 20μg Th/ml may be determined with Eriochrome Black T in acetate buffered solution. Fewer ions interfere if the determination is performed in hydrochloric acid solution, but the lower limit is raised to 1μg Th/ml.

Solvent characteristics in the spectral behaviour of eriochrome black T
Dyes and Pigments, 1994Abstract The visible electronic spectral behaviour of Eriochrome Black T, in a number of organic solvents of different characteristics has been examined. It was concluded that the dye exists in solution in basic solvents (based on their autoprotolysis constant, pK s ) in an azo ⇌ hydrazone tautomeric equilibrium, while in acetone, acetonitrile and ...

Reduction of Silver Ions to a Colloid by Eriochrome Black T
The Journal of Physical Chemistry, 19962-Hydroxy-1-(1-hydroxy-2-naphthylazo)-6-nitronaphthalene-4-sulfonic acid sodium salt (Eriochrome Black T, EBT) dye reduces silver ions in an aqueous solution, producing a stable colloidal suspension. The kinetics of the initial stage, monitored by UV−visible absorbance spectroscopy, are characterized by kinetic equations of a complex form, consisting ...

Eriochrome Black T as a Protein Dye
Nature, 1962BINDING of eriochrome black T to protein was suspected during experimental ultramicro-titration of solutions containing serum proteins, when using eriochrome black T as indicator, because of difficulty in obtaining a value for the indicator blank titration.

Poly(eriochrome black T) modified electrode for electrosensing of methdilazine
Materials Science in Semiconductor Processing, 2020Abstract The current research work is based on the development of an electrode modified by using an indicator, poly(eriochrome black T) (poly-EBT) for the determination of methdilazine hydrochloride (MDH). Excellent electrocatalytic, semiconducting properties of poly-EBT influences the enhanced peak current of MDH.

Photocatalytic Degradation of Eriochrome Black-T Dye by Immobilized Dowex-1x8
Research Journal of Chemistry and Environment, 2023Eriochrome Black-T (EBT) is a commonly used textile dye. It is a harmful organic molecule and is also present in textile effluent. The photocatalytic degradation has been studied using MBIR Dowex-1×8 as the photocatalyst. Some parameters such as pH, light intensity, the amount of photocatalyst and initial dye concentration were also studied.

A novel gel system was obtained by mixing aqueous solutions of tamarind seed xyloglucan (TSX) and Eriochrome Black T (EBT), an antiangiogenic compound. The shear-viscosity flow curves revealed that all the studies mixtures displayed a shear thinning behavior. Viscosity increased with increasing EBT concentrations.

Electroanalysis of theophylline at eriochrome black –T and graphite powder composite electrode
AIP Conference Proceedings, 2018In this study, a selective, simple, and sensitive electrochemical method for the determination of theophylline was proposed based on a composite electrode. Electrochemical analysis of organic drug molecule, theophylline (TP) was investigated at eriochrome black-T and graphite powder composite electrode using different voltammetry techniques. The linear
