Naked-eye detection of fluoride using Zr(IV)-EDTA complex and pyrocatechol violet.
A method for the visual detection of fluoride is presented using an aqueous solution of Pyrocatechol Violet (PV), which changes its color from yellow to blue by the formation of a ternary complex with Zr(H2O)2EDTA; also, the blue color of PV-Zr-EDTA readily shifts to orange red upon the addition of a moderate concentration of fluoride. The mechanism has been interpreted by a ligand-exchange rea...
متن کاملCatalytic Determination of Traces of Tellurium (IV) Using the Reduction of Lauth’s Violet with Sodium Sulfide
A simple, rapid and sensitive method has been developed for determination of traces of tellurium (IV) (7.0-120.0 ng/ml) based on it’s catalytic effect on the reduction reaction of lauth’s violet by sulfide ion at pH 4.2. The reaction is monitored spectrophotometrically by measuring the decrease in absorbance of lauth’s viole at 600 nm by the fixed time method. The detection limit is 5.0 ng/ml a...
متن کاملDetermination of polyhexamethylene biguanide hydrochloride using photometric colloidal titration with crystal violet as a color indicator.
A solution of polyhexamethylene biguanide hydrochloride (PHMB-HCl) was titrated with a standard solution of potassium poly(vinyl sulfate) (PVSK) using crystal violet (CV) as an photometric indicator cation. The end point was detected by a sharp absorbance change due to an abrupt decrease in the concentration of CV. A linear relationship between the concentration of PHMB-HCl and the end-point vo...

15 صفحه اولDetermination of serum proteins by means of the biuret reaction.
In the course of an investigation of the biochemical changes following experimental liver injury we felt the need of a simple, rapid, and accurate method for determining the protein fractions in small amounts of serum. Among the simpler procedures known, the biuret reaction seemed to offer the most encouraging possibilities. Variations and improvements in the application of the biuret reaction ...
