Single and triple solute test solutions were analyzed by a dual
beam spectrophotometer (Lambda 12 UV–VIS photometer, Perkin
Elmer, Germany) in 1 nm steps in the scanning mode for the range
from 220 to 300 nm. Preliminary calibrations confirmed that UV
light absorbance was linearly correlated with the concentrations
of ACS, BTA and DCF, independent from the wavelength.
