Fig. XIII-9. The dependence of the flotation properties of goethite on surface charge. Upper curves are potential as a function of pH at different concentrations of sodium chloride lower curves are the flotation recovery in 10 M solutions of dodecylammo-nium chloride, sodium dodecyl sulfate, or sodium dodecyl sulfonate. (From Ref. 99.)... Fig. XIII-9. The dependence of the flotation properties of goethite on surface charge.

The lower limit of detection is 1 p.g/dm for sodium hexadecyl sulfonate, 2.5 p.g/dm for sodium dodecyl benzenesulfonate and 10 p.g/diW for sodium dodecyl sulfonate with sample volume of O.ldiW. The method proposed is highly sensitive, simple, rapid and guarantees environmental safety of analysis. [Pg.267]

XRD analysis of the solid product showed three main peaks at 28.5 , 47.4 and 56.3 , which indicated that pure crystalline CuCl was formed [3]. Several well-known dispersants polyvinyl pyrrolidone (PVP), sodium hexameta phosphate (SHP), the sodium salt of EDTA (EDTA-Na), sodium dodecyl sulfonate (SDS), and sodium dodecyl benzene sulfonate (SDBS), were introduced to obtain a highly dispersed catalyst. The X-ray patterns obtained with these were basically the same as the patterns obtained with the solids prepared in the other experiments described here. [Pg.326]

Fatty alcohol- (or alkyl-)ethoxylates, CoE, are considered to be better candidates for LLE based on their ability to induce rapid phase separation for Winsor II and III systems. (Winsor III systems consist of excess aqueous and organic phases, and a middle phase containing bicontinuous microemulsions.) However, C,E,-type surfactants alone cannot extract biomolecules, presumably because they have no net negative charge, in contrast to sorbitan esters [24,26,30,31]. But, when combined with an additional anionic surfactant such as AOT or sodium benzene dodecyl sulfonate (SDBS), or affinity surfactant, extraction readily occurs [30,31]. The second surfactant must be present beyond a minimum threshold value so that its interfacial concentration is sufficiently large to be seen by... [Pg.482]

Characterization of the polymer indicates that an application of sodium dodecyl sulfonate as anionic surfactant and sodium persulfate as initiator for both stages leads to a hemisphere particle... [Pg.333]

Fuerstenau and Wakamatsu (1975) examined alumina as a sorbent for dodecyl sulfonate (DS) ions. Alkyl sulfonates, R-SO3, do not participate in substantial ligand exchange reactions with alumina. [Pg.437]

Further evidence for three distinct modes of adsorption can be seen in the electrophoretic behavior of alumina in the presence of sodium dodecyl sulfonate. Below 6 X 10 5M, the electrophoretic mobility is nearly independent of concentration, but at this concentration the slope of the mobility-us.-concentration curve abruptly changes. At 3 X 10"4M dodecyl sulfonate concentration, the electrophoretic mobility reverses its sign, indicating that the charge in the Stem layer now exceeds the surface charge in absolute magnitude. [Pg.173]
