Figure 2

Effect of used media on UV-absorbance. Shown are, as all other compounds behaved similarly, calibration curves for SMX in pure water and the three media R2A-UV, MSM-CN and MSM (Table 2). SMX concentrations were 1.0, 5.0, 10.0, 15.0 and 20.0 mg L^-1. Mean values (n = 3) are shown, standard deviations below 1%. Solid lines were fitted by a linear function with R2 values being >0.99.
