“…The results shown in Table 4 indicate that these values are 2 to 4 times greater than the critical micelle concentration (CMC; determined in this work to be 0.016 % -see Fig. 1, and in good agreement with the value of 0.014 % reported by Misra et al [44]). …”

“…Also, the projected sugar chain may displace the original shear plane mechanically, which causes the decrease in the zeta potential value. Several researchers have observed this type of decreasing trend in the zeta potential value due to the adsorption of the dispersant on solid surfaces. − …”

Effective transportation of fly ash–water slurry through a pipeline from its generation site, a power plant, to a storage site by replacing commercial surfactants such as cetyl trimethyl ammonium bromide and sodium dodecyl sulfate by a natural dispersant extracted from Sapindus laurifolia was studied. The stability of fly ash slurry was determined from its rheological parameters, dispersant concentration, and stabilization mechanism. From surface tensiometric data, the critical micelle concentration of the dispersant was obtained to be 0.017 g/cc. The stabilization of high-concentration fly ash slurry has been studied through its rheological behavior by variation of temperature and dispersant and ash concentration. The rheological result obtained for fly ash concentrations in the range of 50–65% slurry was best justified by the Bingham plastic model. The wettability of fly ash particles is increased in the presence of dispersants, which is inferred from reduction of the surface tension value. The stabilization mechanism of the slurry is explained by a steric factor as indicated by the decrease in the zeta potential value. Air pollution is minimized at its destination site due to agglomeration of fly ash particles, which is confirmed from the SEM microphotograph.

“…Finally the excimer does not form due to the solubilization of the probes in large domains of hydrophobic complexes/micelles. The absence of an excimer peak in the presence of OP-30 premicelles alone is due to its long oxyethylene chain which decreases its relative hydrophobicity [28,54].…”
