Abstract

The present study concerns the synthesis and optimization of layered double hydroxide and their derivatives containing two transition metals, namely iron and copper, which have an important effect in heterogeneous Fenton oxidation by a classical method of a co-precipitation followed by a calcination. The use of experimental design of mixture is to optimize the LDH ratio component. The material was characterized by different methods such as, XRD, SEM, IR, Particles size distribution and UV-DRS. The degradation of the synthetic dye patent blue v was investigated by studying the different effects of parameters such as pH, dye initial concentration, H2O2 dose and photocatalyst loading. The catalytic reaction showed a good performance of oxidation of the dye in a wide range of pH particularly in natural pH. The catalyst kept its activity after several uses, demonstrating its stability and its promising long-term application in the treatment of wastewaters.
