Fluorescence Quenching Studies on Some Substituted Amines by Phenolphthalein
Journal Title: IOSR journal of Business and Management - Year 2018, Vol 20, Issue 8
Abstract
Fluorescence spectroscopy has assumed a major role in analysis, particularly in the determination of trace contaminants is our environment, industries and bodies, because for applicable compounds fluorescence gives high sensitivity and high specificity. In this present work the quenching experiment was done in two different solvents, Diethyl ether and Methanol. Phenolphthalein is taken as the quencher. The fluorescers used for the quenching experiments are some substituted amines [Ethylamine, Diethylamine, Diethylene triamine]. Experimental solutions were prepared by adding fixed aliquot of stock solution of fluorescer to 5 ml of the solvent, so that concentration of resulting solution is about 10-5 M. Quencher solutions were added to these solutions. The fluorescence spectra of fluorescers (Amines) were measured with JASCO model FP-550 spectrofluorometer, operating with 150W Xenon lamp as light source. The various parameters like Stoke’s shift. Ionization potential, electron affinity, molar extinction coefficient and solvent parameter are calculated and tabulated. Based on the observations from the results obtained, it was found that the Phenolphthalein is the best quencher for amines.
