An Economic Magnetic Adsorbent for Acid Blue 80 and Methylene Blue Removal

For the large volumes of dye wastewater treatment, the development of novel adsorbents with high adsorption capacity and good separation is of great significance. Here, a simple method is used to prepare a magnetic adsorbent for the efficient removal of acid blue 80 (AB-80) and methylene blue (MB). The magnetic adsorption results show that as-obtained MEL-Fe-C exhibits good magnetic properties in AB-80 and MB removal experiments. Importantly, this material shows good AB-80 and MB removal property after ten times of repeated use. Therefore, as-prepared MEL-Fe-C is an ideal adsorbent candidate for removal of dyes in wastewater treatment applications.
