“…The adsorption capacity of the other adsorbent (p-DMA) was low at all pH values compared to that of p-DMAC 16 . However its adsorption behavior was similar to that observed for p-DMAC 16 except for low and high pH values (pH 1-2 and pH [10][11][12]. Almost no adsorption of p-nitrophenol onto p-DMA was observed when the adsorption experiments were carried out at pH 11 and pH 12.…”

“…The results show that the partition coefficients increases with increasing length of the side alkyl chain, and are larger for HPG 4 -RBr 13 aggregates than for HPG 17 aggregates. This behavior is in line with what has been reported for distribution of phenols in normal micelles, unimolecular and interpolymer micelles [24][25][26]41]. The relationship between the partition coefficient K X and the standard free energy of transfer from the aqueous phase to the pseudo-micellar phase is given by…”

“…As expected the partition coefficients increases with length of alkyl chain, and the values of K X are larger for F-127 micelles than F-68 micelles. These results agree with data obtained for the partition of phenols in micelles, unimolecular and intermolecular polymer micelles [24][25][26]38 Also, the effect of Pluronic structure on the values of K X follows the trend observed for the solubilization of other non polar substrates, i.e. the partition coefficient increases with increasing PPO content and molecular weight, F-127 > F-68…”

“…The partition coefficients between the aqueous and micellar phases were determined by using the pseudo-phase model. The results are compared with previous work where these model compounds have been used to study normal micelles and intramolecular polymer micelles [24][25][26][27] . In addition, the effect of incorporation of phenols on the micelle structure has been assessed.…”
