Interaction Effect of Operating Parameters during Oxidation of Different Dyes via the Fenton Process. Application of the Plackett-Burmann Design
The interaction effect of eight operating factors on the degradation of three organic dyes of different structures (Cibacron green, methylene blue and methyl orange) has been studied. Effect had been evaluated statistically using the Plackett-Burman screening design which ex-tracted valuable information on the most important parameters and their interactions. The goodness of the model fit was checked by the determination of the coefficient R2.
