Abstract
•It is difficult to compare the dielectric-barrier discharge (DBD) plasma data from different labs.•The major concern is to be able to compare the oxidative strength of the plasma-treated solutions.•We propose to address this issue by developing a simple colorimetric method.•The discoloration of a filter paper dyed with brilliant blue G may be used for direct comparison.
A preliminary study on plasma treatment of dye solutions and dyed paper strips is presented. The discoloration and degradation of all nine organic dyes upon exposure of plasma was observed. UV-vis spectra were used to quantitatively characterize the degradation efficiency of the plasma. Discoloration rates may be used as the parameter for comparison of the oxidation strength of plasma. The oxidation strength of plasma may also be empirically compared using the discoloration of the dyed papers.
The discoloration of a filter paper dyed with brilliant blue G may be used for direct comparison of different plasma systems in their effect on the surface being processed. [Display omitted]
