[ 1 ] - Terbium 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...
[ 2 ] - Selective Cloud Point Extraction and Preconcentration of Copper by the Use of Dithizone as a Complexing Agent
The aim of this work was to develop a selective cloud point extraction method for the separation and preconcentration of copper(II) prior to spectrophotometric determination. For this purpose dithizone was used as a complexing agent and the experimental solution was acidified with sulfuric acid. Triton X-114 was used as a surfactant and after phase separation, based on the cloud point of th...
[ 3 ] - Development and Validation of a Terbium-Sensitized Luminescence Analytical Method for Deferiprone
A sensitive fluorometric method for the determination of deferiprone (DFP) based on the formation of a luminescent complex with Tb3+ ions in aqueous solutions is reported. The maximum excitation and emission wavelengths were 295 and 545 nm, respectively. The effects of various factors on the luminescence intensity of the system were investigated and optimized, then under the optimum conditions,...

[ 5 ] - اندازه گیری اسپکتروفلوریمتری دانو روبیسین با استفاده از تربیوم-دیفراسیروکس به عنوان پروب فلورسانس
یک روش اسپکتروفلوریمتری جدید برای اندازه گیری دانو روبیسین بر مبنای اثر خاموش کنندگی آن بر فلورسانس کمپلکس تربیوم- دیفراسیروکس ارائه شده است. طول موج های تحریک و نشر به ترتیب برابر با 328 و 454 نانو متر می باشند. شرایط بهینه برای اندازه گیری دانو روبیسین بر مبنای اثر پارامتر های مختلف بر کاهش شدت فلورسانس مورد بررسی قرار گرفته است. در شرایط بهینه کاهش شدت فلورسانس با غلظت دارو در محدوده 100 – 1...
