Terbium(III) as a Fluorescent Probe for Molecular Detection of Ascorbic Acid
نویسندگان
چکیده
Fluorescence analysis is a simple and highly sensitive method for detection of small amounts biologically active substances. In this study, complexation terbium(III) chelates with 1,10-phenanthroline ascorbic acid (AA) luminescent properties complexes were investigated. The influence pH solubilization by micellar solutions nonionic, cationic, anionic surfactants on fluorescence was studied. quenching effect terbium ion detected upon an introduction acid. the complex mixed ligands Tb(1,10-phenanthroline)-AA allows limit 7.4 × 10−5 mol·L−1.

KINETIC 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...
