Solvent characteristics in the spectral behaviour of eriochrome black T

Dyes and Pigments, 1994
Abstract 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 ...

Photocatalytic degradation of Eriochrome black-T dye using ZnO nanoparticles

Materials Letters, 2014
In this study, ZnO nanoparticles were synthesized by co-precipitation method. The particles were used for degradation of Eriochrome black-T dye by examination at three different pH values. It was observed that the adsorption of dye onto ZnO nanoparticles surface is strongly dependent on the pH of the solution which plays an important role in ...

Non-extraction flow injection determination of cationic surfactants using eriochrome black-T

Spectrochimica Acta Part A: Molecular and Biomolecular Spectroscopy, 2009
A new, rapid, sensitive, non-extraction batch, and flow injection spectrophotometric method for the determination of cationic surfactants (CSs) such as cetyltrimethyl ammonium bromide (CTAB), tetra-n-butyl ammonium chloride (TBAC) and cetylpyridinium chloride (CPC) is proposed.

Indirect Spectrophotometric Determination of Furosemide using Eriochrome Black-T Dye

Methods and Objects of Chemical Analysis
A simple, economical and sensitive indirect spectrophotometric method for the determination of furosemide in its pure form and in pharmaceutical preparations is described. The method is based on the oxidation of furosemide by permanganate in acidic medium, then the reaction of the remaining potassium permanganate to oxidize the dye Eriochrome Black-T ...

Adsorptive removal and recovery of the azo dye Eriochrome Black T

Toxicological & Environmental Chemistry, 2010
Bottom ash and de-oiled soya have been evaluated as potential adsorbents for the removal of a water soluble azo dye. The characterization of the adsorbents has been performed using infrared spectroscopy and differential thermal analysis. A batch of adsorption method has been adopted for studying the effects of pH, adsorbate concentration, and particle ...

Reduction of Silver Ions to a Colloid by Eriochrome Black T

The Journal of Physical Chemistry, 1996
2-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 ...

CdS and AgBr sensitized Eriochrome Black T (EBT) dye solar cells

Solar Cells, 1985
Abstract The photovoltaic and rectification properties of CdS- and AgBr-sensitized Eriochrome Black T dye solar cells have been studied. The dependence of the short-circuit current and the open-circuit voltage on light intensity and electrode material are examined and the variations with electrode material are explained on the basis of the built-in ...
