I have analysed water and ethylene glycol based multiwall carbon nanotubes (MWCNT) nanofluid with Vol. Concentration of 0.075% at UV-Vis Spectrometery. My samples' absorbance was 2.8 and 2.9 for 350 wavelength. I am here to ask that whether the results of my testing are significant or not. Please guide me in this regard. Thanks
