Normalized absorbance是什么意思
Web17 de set. de 2003 · Specific UV absorbance (SUVA) is defined as the UV absorbance of a water sample at a given wavelength normalized for dissolved organic carbon (DOC) concentration. Our data indicate that SUVA, determined at 254 nm, is strongly correlated with percent aromaticity as determined by 13C NMR for 13 organic matter isolates … WebThe main tool used for routine screening of silver nanowire diameter and wire-to-particle yield is ultraviolet-visible (UV-Vis) spectroscopy. The normalized absorbance near 500 …
