UV-VISPurposeTo observe the change in absorbance at pH 4-12 for fructose at concentrations 0.25mM, 0.75mM and 1.25mM ProcedureThe solutions were made 9/27/2016 The solutions had been in 80C oven for four hours and then sat at room temperature. UV-Vis spectra were taken of each sample from 200-800nm.
0.75mM Fructose pH 12-4 (left to right) 1.25mM Fructose pH 4-12 (left to right) Results
Absorbance v. Wavelength Absorbance at 529nm Absorbance at 394nm
Absorbance v. Wavelength Absorbance at 529nm Absorbance at 392nm
Absorbance v Wavelength Absorbance at 529nm Absorbance at 410nm
