Enhancement of Adsorption of Magenta Dye by Immobilized Laccase on Functionalized Biosynthesized Activated Carbon Nanotubes

In the present study, laccase was immobilized over on activated carbon nanotubes (ACNTs) prepared from Prosopis juliflora bark (PJB) to improve good stability, reusability, and its adsorption performance of magenta dye. The immobilized laccase-ACNTs were characterized by scanning electron microscopy...

Description
Summary:In the present study, laccase was immobilized over on activated carbon nanotubes (ACNTs) prepared from Prosopis juliflora bark (PJB) to improve good stability, reusability, and its adsorption performance of magenta dye. The immobilized laccase-ACNTs were characterized by scanning electron microscopy (SEM) and Fourier-transform infrared spectroscopy (FT-IR). The efficiency of magenta dye (MD) adsorption process was investigated in batch adsorption experiments. Response surface methodology (RSM)-based Box-Behnken design (BBD) was used to optimize the parameters, and the maximum MD adsorption was achieved around 95% at 120 min. The obtained results revealed that the immobilized laccase-ACNTs are a promising composite for degradation of textile dyes.
