Abstract

Macroporous permeable composites with embedded nanoparticles were prepared by cryogelation. Nanoscale particles have large surface area and high surface reactivity and provide cost effective solutions to many challenging environmental remediation problem. Embedding the nanoparticles into polymer or other substrates significantly reduces the risk of free nanoparticles release into the environment. The use of particles at micro size scale has also been investigated. The particles distribution in polymer network, mechanical properties and reactivity of composites were studied. The composite material has a unique structure of large interconnected pores which provide high permeability. Iron oxide nanoparticles and nanoporous carbon microparticles were physically embedded within the macroporous polymer which prevented their release into the environment. The composite devices showed promising results for the removal of the trace concentrations of As(III) from solution and removing trace polar organic contaminants. The interconnected large pores and low flow resistance of macroporous composites make them promising material to be used as a support for micro- and nanoparticles in developing adsorption/filtration devices.
