Photo Physical Properties Caffeine and Cu (II)Caffeine Complex: Developing Derivative Fluorescence Techniques in Analyzing Trac,Used
Delivery time: 8-12 business days (International)
In this project UV/Vis absorption spectra of caffeine in water and dichloromethane, copper sulphate, and mixture of caffeine and copper sulphate in water solution is investigated. UV/Vis absorption spectrum of Cu (II)Caffeine complex is also investigated as a function of time during refluxing to check complex formation. The molar decadic absorption coefficient of caffeine is calculated. Fluorescence emission spectra of Cu (II) Caffeine complex is also investigated and compared with its absorption band. Area normalization analysis method is used. Finally, a better derivative fluorescence method for determination of caffeine content of substances is recommended.
By changing our most important processes and
products, we have already made a big leap forward. This ranges from the
increased use of more sustainable fibers to the use of more
environmentally friendly printing processes to the development of
efficient waste management in our value chain.
