Abstract :The magnetic composite based on layered double hydroxide insert ignore into journalissuearticles values(Fe3O4/NiMn-LDH); was prepared by co-precipitation procedure and considered as a material to eliminate phenol red insert ignore into journalissuearticles values(PR); from aqueous environments. The characterization of Fe3O4/NiMn-LDH were recognized by Fourier transform infrared insert ignore into journalissuearticles values(FTIR); spectroscopy and scanning electron microscopy insert ignore into journalissuearticles values(SEM);. Box-Behnken design insert ignore into journalissuearticles values(BBD); under response surface methodology insert ignore into journalissuearticles values(RSM); were applied to evaluate the effects of the process variables such as pH, adsorbent dosage, and initial PR concentration insert ignore into journalissuearticles values(Co);. The results indicated that a good correlation between the estimated and experimental values was found for the PR decolorization efficiency from aqueous media using Fe3O4/NiMn-LDH insert ignore into journalissuearticles values(R2 = 0.99);. Furthermore, the statistical model obtained from BBD was sufficient to estimate the PR decolorization on Fe3O4/NiMn-LDH insert ignore into journalissuearticles values(p < 0.0001);. The optimal conditions for the PR decolorization efficiency were determined as 5.38, 24.59 mg, and 25.39 mg/L for pH, adsorbent dosage, and Co, respectively which resulted in 86.93% the PR decolorization efficiency. Finally, this work demonstrated that BBD could easefully be utilized for the optimization of the PR decolorization using Fe3O4/NiMn-LDH.
