A NOVEL AND HIGHLY SENSITIVE CATALYTIC METHOD FOR THE DETERMINATION OF ULTRA TRACE AMOUNTS OF CERIUM WITH SPECTROPHOTOMETRIC DETECTION
Cerium (IV) has a catalytic effect on the very slow redox reaction between gallocyanine and bromate in acidic media. The reaction was monitored spectrophotometrically at 525 nm by a fixed time method of 4.0 rnin from initiation of the reaction. The decrease in absorbance at 525 nm is proportional to the Ce (IV) concentration in the range of 0.005-1.000 and 1.00-10.00 pg. ml-l. The limit of ...
متن کاملFlow injection chemiluminescence analysis for highly sensitive determination of noscapine
Noscapine is an antitussive drug and possesses potent antitumor activity. This work establishes a highly sensitive method for its determination by flow injection chemiluminescence (CL) technique. This method is based on its strong sensitizing effect on the weak CL reaction between sulfite and acidic permanganate. The mechanism for the sensitizing process is proposed on the basis of fluorescence...
متن کاملAutomatic semi-microcolumn liquid chromatographic determination of catecholamines in rat plasma utilizing peroxyoxalate chemiluminescence reaction.
A fully automated and highly sensitive method with a semi-microcolumn liquid chromatography system for the determination of rat plasma catecholamines (CAs) was developed. Automated on-line extraction of CAs in diluted plasma using a precolumn packed with strong acidic cation exchange resin was coupled with separation of CAs on a semi-microcolumn (250 x 1.5 mm id). fluorogenic derivatization wit...
متن کاملTerbium Sensitized Chemiluminescence Method for the Determination of Rabeprazole -Application to Pharmaceutical Analysis and Dissolution Studies
A simple and sensitive chemiluminescence-based method was established for the determination of rabeprazole.The proposed method was based on the enhancing effect of rabeprazole on Ce(IV)-Na2SO3 -Tb(III) chemiluminescence reaction. A possible mechanism was discussed for chemiluminescence system by studying UV-Vis, fluorescence and chemiluminescence spectra. The effects of va...
متن کاملA Highly Sensitive Kinetic Spectrophotometric Method for the Determination of Ascorbic Acid in Pharmaceutical Samples
In this study, a new reaction system for quantitative determination of ascorbic acid was introduced. The developed method is based on inhibitory effect of ascorbic acid on the Orange G-bromate system. The change in absorbance was followed spectrophotometrically at 478 nm. The dependence of sensitivity on the reaction variables including reagents concentration, temperature and time was investiga...
