【 摘 要 】

The discharge of industrial wastewater containing dyes is a matter of concern because dyes have harmful effects on the environment and human health. In this work, a novel magnetic separation agent of Fe3O4/poly (acrylamide-acryloyloxyethyl thimethylammonium chloride) [MCPAM] was designed for high-performance removal dyes by taking advantage of magnetic separation property of Fe3O4 nanoparticles. MCPAM was synthesized through inverse emulsion polymerization and the optimal reaction conditions were obtained by orthogonal experiments. The shape and size of MCPAM was detected by transmission electron microscopy (TEM). The chemical bonds and functional groups of MCPAM were measured by fourier transform infrared spectroscopy (FT-IR). The magnetic properties of MCPAM was surveyed by Superconducting Quantum Interference Device (SQUID MPMSXL). The magnetic separation performance of MCPAM was studied through detecting the removal efficiency of reactive red dye X-3B. The results showed that the MCPAM had core-shell structures and good magnetic properties. And the MCPAM has great potential in accelerating solid-liquid separation and improving removal efficiency of pollutants such as dye colloid in wastewater.
