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 کاملextremal region detection guided by maxima of gradient magnitude
a problem of computer vision applications is to detect regions of interest under dif- ferent imaging conditions. the state-of-the-art maximally stable extremal regions (mser) detects affine covariant regions by applying all possible thresholds on the input image, and through three main steps including: 1) making a component tree of extremal regions’ evolution (enumeration), 2) obtaining region ...
Unexpected random urinary protein:creatinine ratio results–limitations of the pyrocatechol violet-dye method
BACKGROUND For clinicians, it is important to rely on accurate laboratory results for patient care and optimal use of health care resources. We sought to explore our observations that urine protein:creatinine ratios (PrCr) ≥30 mg/mmol are seen not infrequently associated with normal pregnancy outcome. METHODS Urine samples were collected prospectively from 160 pregnant women attending high-ri...
متن کاملUsing Taguchi Method to Optimize Recovery of Bismuth by Electrolysis
This paper presents a methodology, based on the taguchi parameter design approach, for the optimization of process parameters for bismuth recovery from aqueous solutions. The process parameters considered are [Bi3+], [NaCl], temperature, and cathodic current density. In addition, cell voltage and current efficiency as two responses have been considered. An orthogonal array L9, the signal-to-noi...
متن کاملDesign and Evaluation of a Novel Bismuth Optical Sensor Using PC-ANN Application
The characterization of and construction of a new optical sensor based on the immobilization of Pyrocatechol Violet on a triacetylcellulose membrane was described to for the determination of bismuth (III) in real samples. The interaction between sensing membrane and bismuth (III) was caused at pH 3.80 in acetate buffer solution and the color changed from yellow to blue along with the appearance...
