COBALT PHTHALOCYANINE MODIFIED CARBON PASTE ELECTRODE AS A POTENTIOMETRIC SENSOR FOR DETERMINATION OF ASCORBIC ACID
A carbon Paste electrode modified with cobalt (II) phthalocyanine (CoPC) was used as a sensitive potentiometric sensor for determination of ascorbic acid in aqueous solutions. The potential response of the electrode is a linear function of ascorbic acid concentration over the range 5 10 to 10 M (?1- 1800 µg ML ) with a Nernstian slope of 56 mV at pH 7. The limit of detection was 0.2 µg ...
متن کاملNile 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 کاملDetermination of pKa values of alendronate sodium in aqueous solution by piecewise linear regression based on acid-base potentiometric titration☆
As a mono-sodium salt form of alendronic acid, alendronate sodium presents multi-level ionization for the dissociation of its four hydroxyl groups. The dissociation constants of alendronate sodium were determined in this work by studying the piecewise linear relationship between volume of titrant and pH value based on acid-base potentiometric titration reaction. The distribution curves of alend...
متن کاملIndirect potentiometric titration of ascorbic acid in pharmaceutical preparations using copper based mercury film electrode.
A simple and rapid potentiometric method for the estimation of ascorbic acid in pharmaceutical dosage forms has been developed. The method is based on treating ascorbic acid with iodine and titration of the iodide produced equivalent to ascorbic acid with silver nitrate using Copper Based Mercury Film Electrode (CBMFE) as an indicator electrode. Interference study was carried to check possible ...
متن کاملColloidal titration of aqueous zirconium solutions with poly(vinyl sulfate) by potentiometric endpoint detection using a toluidine blue selective electrode.
Zirconium oxy-salts were hydrolyzed to form positively charged polymer or cluster species in acidic solutions. The zirconium hydrolyzed polymer was found to react with a negatively charged polyelectrolyte, such as poly(vinyl sulfate), and to form a stoichiometric polyion complex. Thus, colloidal titration with poly(vinyl sulfate) was applied to measure the zirconium concentration in an acidic s...
