Uv-VisPurposeTo observe the change in absorbance at pH 4-12 for fructose at concentrations 0mM, 0.0625mM and 0.125mM ProcedureSolutions were made 09/14/2016 0.0625mM fructose 4-12pH (left to right)
0.125mM fructose 4-12pH (left to right)
0mM fructose 12-4pH (left to right)
ResultsWavelength at 0mM Fructose
Peak at 538nm for 0mM fructose
Wavelength at 0.0625mM Fructose
Peak at 538nm for 0.0625mM Fructose
NotesThe 0mM fructose at pH11, and the .0625mM fructose pH11 had nanoparticles collected at the bottom the test tube and were mixed in before running UV-VIS on the samples. None of the other samples had this. | |
