Quantitative analyses were performed using external standards n-dodecylbenzene was used for LABs n-C21 fatty acid methyl ester for LASs n-TBP for APs phenanthrene and chrysene for PAHs coprostanol and PCBs congeners lUPAC Nos 28, 52, 101, 118, 138, 153 and 180. NPEOs were quantified, using the NPE30, from the FID profile in coastal waters and from the HRGC-PICESIM trace for wastewaters . In both cases the same response factor was assumed for all the oligomers (1-7).

In contrast to TPS with its branched alkyl chain, n-dodecylbenzene sulfonate exhibits an extremely fast rate of biodegradability. The change-over from a branched to a straight-chain structure is easily achieved, and thus by the use of Ziegler synthesis and molecular-sieve extraction techniques, industrial processes for the production of linear olefines and -alkanes soon became readily available. These are the basic starting materials for the synthesis of linear alkylbenzene derivatives.

The polarity of the insulating matrix plays a critical role in the miscibility of the insulating matrix/conducting polymers blends. The adhesion between non-polar PE and polar ICPs suffer due to this disparity. In order to improve the compatibility between the polymer components, low density PE was blended with p-toluenesulfonic acid, phenolsulfonic acid or camphorsulfonic acid doped polyaniline in the presence of functionalized metallocene PE, a compatibilizer [56]. The components were fed into a co-rotating twin-screw extruder at 200 C. Blending was xmdertaken at a screw speed of 60 rpm under nitrogen atmosphere. Castillo-Castro et al. (2011) have prepared n-dodecylbenzene sulfonate doped polyaniline/ low... 

While an increase in the hydrocarbon chain length in a series of normal alkyl surfactants between Cg and C20 will have a minor effect on the effectiveness of a surfactant, other structural changes can produce much more dramatic effects. We have seen that structural features such as branching and multiple-chain hydrophobes will generally result in increases in the cmc of surfactants with the same total carbon content. Those changes seem to have a much smaller effect on the efficiency of the surfactant (C20) than on its effectiveness. For sodium n-dodecylbenzene sulfonate the cmc and are 1.2 x 10 M and 36 mN/m, while the same values for sodium(2-methylundecylbenzene)sulfonate are 2.3 x 10 M and 27 mN/m, respectively.
