“…In a second step, the diazotized PUF is coupled with selected compounds to obtain the functionalized PUF (Burham et al 2006). When small pieces (<5 mm) of PUF are used, micro-polyurethane-functionalized foam is obtained and can be used for sorption and preconcentration of several chemical compounds (Azeem et al 2013). Table 4 shows some examples of the use of functionalized PUF in the removal of organic compounds and metal ions.…”

Polymeric materials have had an exponential growth since the Second World War, so that in 2018 the annual world production was 359 million tons. This has generated a contamination problem because of its prolonged exposure to various chemical and environmental factors which have caused the formation of particles with a size less than 5 mm with a vast surface area and chemically stable and adjustable surface. For these reasons, these particles called microplastics (MPs) have been used as vectors for chemicals in the environment and, recently, in the removal of several pollutants from water. In this chapter, some representative examples of the use of microplastics for sorption of contaminants from water (pharmaceuticals, metal ions, and other organic compounds) are shown. The chapter is organized into two parts: the first part addresses MPs of commercial origin (virgin) and those reused after being

In this research, a new derivative of core-shell magnetic chitosan biopolymer was prepared. The core magnetic Fe 3 O 4 nanoparticles were synthesized by a simple and fast sonochemistry route within 10 min. Fe 3þ ions and sodium thiosulfate were used as the iron source and reducing agent, respectively. Then shell chitosan grafted with 5-acrylamido-1,10-phenanthroline was cross-linked to the magnetic core with glutaraldehyde. The new material was characterized with transmission and scanning electron microscopy, infared spectroscopy, X-ray diffraction, thermogravimetry and vibrating sample magnetometer technique. The characterization analysis revealed that grafted chitosan had been assembled on the surface of magnetic nanoparticles at a high density and showed enough magnetic response for magnetic separation. The prepared composite was used for the removal of Pb and Cu ions from environmental samples. The adsorption capacity within 10 min interaction time was 111.0 and 33.3 mg g À1 for Pb(II) and Cu(II), respectively.
