Sample text

The majority of the studies involving ‘environmental’ particles have used synthetic laboratory particles such as goethite [151], haematite [97,113,154], montmorillonite [166] or fractionated organic compounds [158–165,167–169]. The few examples of fractal concepts being applied to non-fractionated environmental samples concern the characterisation of marine snow [170,171], aggregates formed in a mesocosm diatom bloom [172,173] and estuarine and marine suspended particles [174–177]. Some relevant published results are collated in Table 4.

Since the colloid aggregation rate is proportional to the square of the particle concentration [16], the collision frequency in nanosystems will be many orders of magnitude higher than for larger colloid particles. 2 CHARGE Most colloidal particles are charged. e. silica, iron oxyhydroxides, humics, bacteria), (ii) lattice imperfections at the solid surface and isomorphous replacements within the lattice (aluminosilicates) and (iii) ion adsorption. At pH values close to neutral, most natural particles, such as aluminosilicates, and most insoluble oxides, organic compounds, bacteria and algae are characterised by a negative surface potential, as indicated by negative M.
