Triton X-100 surfactant

A method has been published for the determination of a variety of metals in diluted blood and serum using inductively coupled plasma atomization with mass spectrometric detection.3 Blood was diluted tenfold and serum fivefold with a solution containing ammonia, Triton X-100 surfactant, and EDTA. Detection limits adequate for measurement in blood or serum were found for cadmium, cobalt, copper, lead, rubidium, and zinc. 

Heat-Induced Aging. Linen samples (12 x 4 ) were washed in deionized water containing 0.1% Triton X-100 surfactant, rinsed, and air dried. The samples were aged at 180°C in a forced draft laboratory oven for 1, 3, 5 or 10 hrs. The samples were removed from the oven and conditioned at 21<>c and 65% RH prior to testing. 

A more detailed study on foam behaviour and the features of foam column destruction has been performed in [69-71]. Various kinds of surfactants, different foam column heights, foam dispersity and temperatures, were investigated at Ap pgH, including the range of critical pressure drops pcr. The kinetics of establishing a capillary pressure was also accounted for. Used were ionic (NaDoS) and nonionic (Triton-X-100) surfactants as well as some silicon-organic compounds which differed by the number of siloxane, dimethylsiloxane, oxyethylene and oxypropylene groups (KS-1, BS-3 and KEP-2). 

Triton X-100 surfactant (Rohm and Haas, Philadelphia, PA). The surfactemt minimized electroosmotlc flow. The terminating electrolyte was 0.01 H H-hexanolc acid (Kodak) and contained 0.5% Triton X-100 surfactant (purified by fractional distillation). The Triton X-100 surfact2uit was purified by dialysis to remove low-molecul u -welght anionic impurities.

In another work, Z. Chen et al. have added dropwise diluted bromine to Triton X-100 suspended SWNTs and SWNT bundles and observed sedimentation of tube material enriched in metallic SWNTs [128]. No enrichment was observed for experiments using sodium dodecyl sulfonate as surfactant. The authors take this experimental fact as evidence that the enrichment mechanism involves bromine-induced destabilization of the Triton X-100 surfactant shell, with greater specificity for metallic SWNTs. 

Titanium alkoxides have been used by various workers as the source of titanium for the synthesis of Ti02 particles via microemulsions. In an early work reported by Guizard et al. [260] a reverse microemulsion was prepared by mixing Triton X-100 (surfactant), decane (oil phase) and water Ti-tetrabutoxide or tetraisopropoxide was added to it for precipitation of particles. 

The MTT is reduced to formazan by the NADH, which is generated in the NAD-dependent lactate dehydrogenase reaction. The presence of detergents such as Triton X-100 surfactant (alkylaryl polyether alcohol) accelerates the reduction of the tetrazol-ium salt manifold. After an additional incubation inhibition zones become visible. The antibacterial compounds appear as clear spots on the colored formazan background. 

Lucigenin ECL has also been extended to surfaces [19]. Self-assembled mono-layers (SAMs) modified electrodes and solutions containing Triton X-100 surfactant molecules caused the enhancement in ECL of lucigenin. 

The data for various ionic and nonionic (Triton X-100) surfactants are given in Table 1 as examples [4). It is conclusively observed that ionic micelles (e.g. n-CgSO Na,...

Microemulsions comprising [bmim][PF j as lipophilic component and water stabilized by Tween-20 and by Triton X-100 surfactants were reported [40,41]. UV-Vis absorption spectra indicated that the polarity of the water domains in water-in-[bmim][PFg] reverse microemulsions was lower than that of bulk water. The experimental results indicated that the water domains were sufficiently well formed to support the solubility of conventional electrolytes in the water-in-[bmim][PFJ microemulsions, and spectroscopic data indicated that the ionic species were in the aqueous pseudophase. It was demonstrated that the hydrodynamic diameter of the [bmim][PFg]-in-water microemulsion droplets was nearly independent of the water content but increased with increasing [bmim][PFJ content due to the sweUing of the micelles by the IL. The size and morphology of IL droplet in the microemulsion depend on the water content (molar ratios of IL/TX-100), and the diameter of droplet increased with the water content as shown in Figure 18.4. The diameters of 40-47, 50-53, 55-57, and 83-90 nm were for the ratios of 0.2, 0.5, 1.0, and 1.5, respectively [29]. The surfactant aggregate sizes were somewhat higher than that of conventional microemulsions.
