原始语种摘要: Abstract(#br)Because of its superior physical and chemical properties, MnFe 2 O 4 is regarded as one of the best magnetic material alternatives for Fe 3 O 4 . However, MnFe 2 O 4 alone cannot remove heavy metal ions and dyes. Here, we report on a new mesoporous magnetic MnFe 2 O 4 @CS-SiO 2 microsphere material that was synthesised via the hydrothermal method to remove Zn 2+ and methylene blue (MB) in simulated textile wastewater. The composite was characterised using a vibrating sample magnetometer, scanning electron microscopy coupled with energy-dispersive X-ray spectroscopy, X-ray powder diffraction, Fourier transform infrared spectroscopy, X-ray photoelectron spectroscopy, and a Brunauer-Emmett Teller analysis. The pH, adsorbent dosage, initial adsorbate concentration, and reaction...
