Polymer–clay nanocomposites for the removal of trichlorophenol and trinitrophenol from water

Novel polymer/surfactant modified montmorillonite hybrids and the implications for the treatment of hydrophobic organic compounds in wastewaters

“…Comparing with C-Mt, 46P-Mt shows a rather weak sorption capacity towards phenol, which indicates that PDADMA can provide rather limited sorption sites for phenol at this loading level. Although P-Mt has been used as sorbents for organic compounds in several reports, the amounts of PDADMA used in those investigations were much larger, and also the sorption capacity showed selectivity (Churchman, 2002;Ganigar et al, 2010). Fig.…”

“…The polymer PDADMA is selected because of its low cost (about 25% of CTMA) and commercial availability. It has also been used to intercalate montmorillonite (Churchman, 2002;Ganigar et al, 2010;Shen et al, 2009;Souza and Nascimento, 2008). The structural characteristics of the CTMA and PDADMA synthesized organo montmorillonites (C/P-Mt) will be investigated, and their sorptive characteristics towards phenol will also be examined.…”

Designing a regenerable stimuli-responsive grafted polymer-clay sorbent for filtration of water pollutants

“…In addition, the pyridine group of the polymer can be further functionalized to improve composite performance [13,14]. Indeed, adsorbed functionalized PVP–MMT composites were efficient sorbents for filtration of a variety of pollutants including dissolved organic matter [14], pyrene [15], phenolic derivatives [16], pharmaceuticals [13] and pesticides [12,17]. …”

Preparation and Mechanical Properties of Polymeric Nanocomposites with Hydroxyapatite and Hydroxyapatite/Clay Mineral Fillers - Review

“…Polymer/clay mineral composites are widely used in recent years, and also the exploration of this topic is significant. It was many times proven that addition of small amount of clay mineral in to the polymer matrix improves the mechanical properties of polymer [11][12][13].Combination of polymer, hydroxyapatite and clay mineral leads to the composite with unique properties and wide range of application, especially in the medicine, since the non-living, inorganic chemical make-up of our teeth and bones is primarily composed of hydroxyapatite (Figure1).In this review the main aspects of apatitic calcium phosphates are presented. Focus is here on basic preparation techniques and their limitation, properties of prepared nanocomposites and draft-possibilities of application.…”
