From this information, the absorbance of the sample is determined for that wavelength or as a function for a range of wavelengths. Sophisticated UV spectrophotometers can perform automatically. However, such UV spectrophotometers have very complicated structures, very costly, and usually bulky (not ...
Absorbance of the filtrate was then measured using a U-3501 Shimadzu UV-vis-NIR spectrophotometer at the wavelength maximum of RhB (λm ax = 500 nm). The concentration of RhB that remained in the sample solution was calculated from a calibration curve. The percentage of RhB ...
