We have investigated the availability of phenanthrene, intercalated into a montmorillonite clay saturated with tetradecyltrimethylammonium (TDTMA) cations, as a carbon and energy source to two bacterial species. When phenanthrene was provided in the

Formation and Properties of Clay-Polymer Complexes provides a comprehensive account of the reactions between clay minerals and organic polymers. The book opens with a discussion of the structures of common clay minerals, clays colloid chemistry, and
Clay minerals are abundant, inexpensive, and generally safe materials for environmental applications. Because of their large specific surface area, high porosity, surface charge, and surface functional groups, clay minerals function as adsorbents, fi

This chapter discusses the theoretical and practical aspects of the clay–polymer interaction. Uncharged polymers adopt a ‘train–loop–tail’ surface conformation, giving high-affinity type isotherms and little desorption on dilution. Their ad

Here we discuss the formation and properties of clay–polysaccharide complexes. Cationic and non-ionic polysaccharides are strongly adsorbed by clay minerals and can penetrate the interlayer space of montmorillonite. Anionic polysaccharides are weak

This chapter describes the interactions of clay minerals with uncharged (nonionic) polymers, such as poly(vinyl alcohol), polyacrylamide, polyethylene glycol (polyethylene oxide) and polyvinyl pyrrolidone. Although ion–dipole, hydrogen bonding and

This chapter describes the formation and properties of complexes between clay minerals and positively charged polymers (polycations). These polymers are strongly adsorbed and intercalated by smectites through a cation exchange process, giving rise to

This chapter reviews the interactions of clay minerals with negatively charged polymers (polyanions). Because of coulombic repulsion, polyanions interact only weakly with negatively charged clay mineral surfaces. Nevertheless, appreciable adsorption

This chapter summarizes the interactions of clay minerals with viruses and bacteriophages. Below the isoelectric pH of the virus, adsorption to clay minerals is largely effected through electrostatic interactions. Above this pH, van der Waals interac
