The present chapter highlights recent developments in photocatalysis that are pertinent to its potential process applicability in water treatment for organic contaminants specifically, (i) mechanism understanding, intermediates and stoichiometry of the overall process (ii) its generality for complete contaminant destruction (mineralization) (iii) some specific contaminant classes of interest (chlorinated aromatics, surfactants, herbicides and pesticides) (iv) kinetics (equations, surface vs. bulk reactions) (v) influence of additional oxidants (vi) use of solar vs. artificial illumination (vii) different catalysts and catalyst s forms (suspended vs. immobilized) (viii) photoreactor design (ix) comparison with other techniques using oxidants and light, with care to the evaluation of efficiency and economics.

The possible interactions of proteins (globular) and water-soluble lipids with a synthetic emulsifier have been recognized and studied. Proteins have a strong affinity toward both polar lipids and aromatic surfactants. Their interactions with nonionic surfactants are very limited. Proteins also strongly interact with water-insoluble polar lipids (electrostatically dependent interaction). [Pg.357]

This finding provides a new and simple approach to directly control the assembly of fijllerene-containing polymers using aromatic surfactants, which may find important appUcations in drug delivery, nanoscale patterning, rriiniaturized biological devices and many others. [Pg.73]

Recall that clay 1 is a commercial clay with an aliphatic quaternary ammonium ion while clay 2 contained an aromatic surfactant possessing the same norbomene end group as the PMR polyimide resin. In the latter case, the norbomene end group can potentially participate in crosslinking reactions with the PMR resin. Such reactive clay treatments have been reported to... [Pg.2337]
