Modélisation et optimisation par les plans box-behnken et composite centre de la dégradation photocatalytique du colorant bleu basique 41 par ZnO dans un réacteur solaire et un réacteur A lumiere artificielle

Abstract

Abstract The pollution caused by the use of textile dye lead to the necessity for the use of degradation processes such as Photocatalysis which is an advanced oxidation processes, based on the activation of semiconductor ,these conductors used are Oxide of the zinc (ZNO) and bleach (NaClo) which are considered a catalyst with light radiations and wave’s length of 608 nm. The application of experimental design methods allows us to express the modeling and optimization of the degradation of basic blue 41 dye in artificial light reactors also solar reactor and to assess the influence of three parameters which are catalyst concentration [ZNO], dye concentration [BB41] and accumulation using the Central composite design and the Box-Behnken design
