“…Their procedure described in the following lines. The thickness of ethoxy number distribution as seen by Fast Atom Bombardthe oxide layer (either SiO 2 or TiO 2 ) was determined in air ment mass spectrometry (22,23) is close to that of nonionic or solvent by the four-zone method which cancels most of surfactants in the case of NPE4S and NPE10S, but much optical imperfections of both apparatus and cell windows more flattened in the case of NPE25S (24). Due to their (33).…”

“…However, the mass loadings indicated above suggest that even at these removals, appreciable amounts are released to receiving waters. Thus, Ventura et al (15) identified LAS and a variety of other anionic, cationic, and nonionic surfactants in surface and drinking water extracts. In view of all these effects, efforts are being made to remove the anionic surfactants in natural waters.…”

This study was undertaken to evaluate the efficiency of rubber granule, a low-cost adsorbent for the removal of sodium dodecyl sulfate (SDS) that is a representative member of anionic surfactant (AS). In the batch experiments conducted at an initial concentration range of 2-6 mg/l, it was found that the rubber granules selected could remove SDS from water up to 90%. Kinetic profiles were developed for various conditions. Effects of adsorbent size, initial adsorbate concentration and adsorbent dose, pH, Ca2+ ion concentration, Fe2+ ion concentration, Cl- ion concentration, and ionic strength on the adsorption of SDS on rubber granules were studied. The adsorption isotherm studies were also conducted.

“…During the 1980s and early 1990s several reports on the use of FAB/MS for identifying surface-activeagents (surfactants) in commercial product [3][4][5][6] and environmental samples [7][8][9][10] appeared in the literature. The majority of reports describe the use of FAB/MS for the qualitative analysis of surfactants while only a limited number of reports describe the quantitative analysis of surfactants by FAB/MS [7][9] [11].…”

“…Compared to LC/MS/MS, FAB/MS is faster and less complicated. With the publication of a table of characteristic ions acquired under positive ionization mode, Ventura et al [10] made it possible to quickly identify many classes of commonly-used surfactants that are used in specialty chemical formulations.…”

Hydrocarbon-and fluorocarbon-based surfactants are used in specialty or 'niche' chemical formulations that are designed for applications such as aircraft deicing and anti-icing, 'spreaders' that increase the effectiveness of pesticide formulations, and for fighting hydrocarbon-fuel fires. The identity of the surfactants in specialty formulations is usually proprietary information. However, this information is needed to design studies that monitor the occurrence and fate of all the components of specialty chemical formulations that enter the environment and pose a risk toward aquatic organisms. Fast atom bombardment/mass spectrometry (FAB/MS), while not a new technique, remains the fastest technique for identifying surfactants in complex mixtures because no sample preparation is required. FAB/MS was applied to samples of an aircraft deicer and anti-icer and aqueous-film-forming-foams (AFFF) for the purpose of identifying the major classes of hydrocarbon and fluorocarbon surfactants. High mass accuracy FAB/MS measurements were made to identify an unknown fluorosurfactant in an AFFF formulation. Rapid identification of surfactants that are released into the environment facilitates the subsequent selection of quantitative analytical methods that can be used to monitor the occurrence and fate of surfactants in the environment.
