What is Electric Field Assisted Assembly of Nanoparticle Loaded Microspheres Toward Industrial Applications for Organic Dye Removal about?

Immobilization of nanoparticles (NPs) is indispensable for its industrial application to avoid the flying, aggregation and secondary pollution. This study reported a simple but robust immobilization method to assemble NPs to microspheres (MSs) supports assisted by electric-field. The size of MSs can be well controlled via adjusting electric field strength. The immobilization of NPs in calcium alginate (CA) MSs by electric field assisted technique (EFAT) can dramatically enhance the dye removal efficiency of NPs. The effect of operating conditions on the dye removal performance of MSs was also studied, showing that the size of SiO2@CA MSs can be adjusted according to the specific requirements for practical applications without worsening the dye removal performance with this EFAT. To evaluate the potentials of the prepared SiO2@CA MSs toward industrial applications, the performance of the MSs in a Taylor-Couette (TC) reactor was investigated by CFD simulation. The effects of key parameters including rotation speed of TC reactor and the size of SiO2@CA MSs were studied to demonstrate the compatibility between MSs and TC reactors. This study could provide guidance to the production of
