Detection of Ascorbic Acid in Biological Samples by a New Modified Glassy Carbon Electrode
The present work describes the construction of a new modified electrode by casting the appropriate mixture of a metallocene, which has been introduced in the experimental part, as a mediator at the surface of glassy carbon (GC) electrode. The proposed modified GC electrode was used for the determination of ascorbic acid (AA) in phosphate buffer (PB) solution (pH = 4.0). When compared to bare GC...
متن کاملdetection of volatile compounds of medicinal plants with some nano-sorbents using modified or new methodologies and investigation of antioxidant activity of their methanolic extracts
in this work, a novel and fast method for direct analysis of volatile compounds (davc) of medicinal plants has been developed by holding a filament from different parts of a plant in the gc injection port. the extraction and analysis of volatile components of a small amount of plant were carried out in one-step without any sample preparation. after optimization of temperature, extraction time a...
Nile Blue- Chitosan Composite as a new Electrochemical Sensor for Uric Acid on Glassy Carbon Electrode
Nile blue-Chitosan NB-CH as a new type of organic days-organic composite was made using Nile blue and chitosan. The NB-CH composite was made using a 0.005 M solution of Nile blue NB and a 7 solution of chitosan. To do this, a mixture of Nile blue and Chitosan with the ratio of 2:1 was prepared. The electrocatalytic oxidation of uric acid UA has been studied on glassy carbon electrode by NB-CH u...
متن کاملA New Overpotential — Capacitance Mechanism for H2 Electrode
The H2 electrode is commonly assumed to be a half-cell, 2 H + 2e == H2, and explained by the Nernst equation. We cannot assume that the H is easily reduced to H2 in an H2 saturated solution, and H2 becoming oxidized to H in a strongly acid solution against the equilibrium principle. How can the H2 gas is involved from a basic solution where there is practically no H ions? Another equilibrium ha...
متن کاملKINETIC DETERMINATION OF ASCORBIC ACID a WITH SPECTROPHOTOMETRIC DETECTION
A simple and rapid method has been developed for the determination of ascorbic acid in fruit and pharmaceutical products. The method is based on the measurement of the reaction rate between ammonium molybdate and ascorbic acid in acidic media. The reaction was monitored spectrophotometrically at 800 nm by fixed-time and variable-time methods. The calibration graph was linear in the range of...
