1 ,4-benzoquinone modified carbon paste electrode is used for the determination of caffeinernin coffee by square wave voltammetry, Voltammetric studies showed that the peak currentrnof l,4-benzoquinone decreases with increasing the concentration of caffeine. The effects ofrnpH, electrode composition, step potential, pulse amplitude and square wave frequency onrnthe voltammetric response were thoroughly investigated, and it was found that 1,4-rnbenzoquinone exhibits excellent behavior, intenns of very well-defined, reproduciblernvoltammetric peaks for caffeine determination. The results enabled the measurement of thernpeak current of l,4-benzoquinone for the determination of caffeine content in coffee.rnPromising results were obtained for caffeine determination in real samples
Subsurface Intelligence & Critical Mineral Exploration
Modern Geology projects now focus on Machine Learning in Mineral Targeting, Carbon Capture & Storage (CCS) Geologic Modeling, and Critical Mineral Systems (Lithium, REEs). If your research involves Hydrogeological Connectivity, Seismic Inversion, or Geotechnical Site Characterization, ensure your analysis follows the JORC or NI 43-101 reporting standards and utilizes robust 3D Subsurface Visualization and Geochemical Fingerprinting frameworks.
