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 three organic dyes different structures (Cibacron green, methylene blue and methyl orange) has been studied. Effect had evaluated statistically using Plackett-Burman screening design which ex-tracted valuable information most important parameters their interactions. goodness model fit was checked by determination coefficient R2. process factors, affected efficiency dyes, were then analyzed illustrated; valueі (p F) for proved validity model. results interactions between allow to understand study impact each parameter elimination distinguish key factor upgrade Fenton process.
