Abstract EN
The effect of radiation on the color intensity of aerated, oxygen and nitrogen-saturated aqueous solution of ethyl violet (EV) has been investigated.
The radiation degradation yield (Gd values) were found to be (0.087, 0.072 and 0.061) and (0.0006; 0.0043 and 0.0034) (mol/J, for aerated aqueous and dimethyl sulfoxide solutions, respectively.
The relatively low degradation yield indicates the absence of chain reactions, and probably the poor efficiency and economics, in terms of the practical application of the radiation process.
For applications in the radiation treatment of waste water, it was noted that in the presence of oxygen and at higher concentration of EV, the value of Gd increased markedly, so that it may be practical to monitor the extent of sterilization of water.
In addition, the radiation processing of EV waste water may also become economically feasible.
The effect of pH, light and temperature on pre- and post-irradiation stability have been studied.
Suggestions are made for the possible use of EV aqueous and DMSO solutions as a chemical dosimeter in the range of absorbed dose 0.25 and 20 kGy respectively.
