“…Traditional techniques solid-liquid extraction [46], extraction in Soxhlet apparatus [5,28,47] and ultrasonic extractions [48][49][50] are required the use of high amount of organic solvent. The analytes were extracted with use of pure methanol or as mixture with other solvents (acetone, dichloromethane) [5].…”

“…Analysis of different types of environmental samples confirmed occurrence of compounds from the group of anionic surface active agents in different ecosystems. Mainly, in liquid and solid samples, were determined total concentrations of anionic analytes [49,50,71] or individual linear alkylbenzene sulfonates [28,55,72]. There are few papers about determination also (beyond LAS) individual AES and AS in solid matrices [5,48,57,73].…”

Abstract:Surface active agents (SAA) with negative charge of polar group are named as anionic compounds. They are the main constituent of most products containing synthetic surfactants. The linear alkylbenzene sulfonates (LAS), alkyl ethoxysulfates (AES) and alkyl sulfates (AS) are typically applied from this class of compounds. Those surfactants are ingredients of household detergents and cleaners, laundry detergents, cosmetic etc. Moreover they can be applied in the paper, textile and tanning industry as optical brighteners, dispersant, wetting and suspending agents. They can be substrates in the formulation of different products like dyes, pigments, pesticides, exchange resins, plasticizers and pharmaceuticals. Anionic surfactants after use are passed into sewage-treatment plants, where they are partially degraded and adsorbed to sewage sludge (applied in agriculture fields). Finally, the anionic SAA or their degradation products are discharged into surface waters and onto bottom sediments, soils or living organisms. Therefore, it is important (widely application, bioaccumulation, toxicity for living organisms) to investigate the environmental fate of those class of compounds in more details. This research involves determination the concentration of anionic surfactants with use appropriated analytical techniques in environmental samples The official methodology for determination of anionic SAA in liquid samples is based on the ion-pair reaction of these analytes compounds with methylene blue (MB) and an extraction with toxic solvent chloroform. During isolation step of anionic compounds from solid samples are employed Soxhlet and ultrasonic-assisted extraction techniques with use of methanol or mixture of other organic solvents as extraction medium. To overcome disadvantages of those traditional techniques were applied following techniques at sample preparation step from liquid and solid matrices: solid-phase extraction (SPE) and solid-phases microextraction (SPME); accelerated solvent extraction (ASE), microwave-assisted extraction (MAE), supercritical fluid extraction (SFE), respectively. For estimate total concentration of anionic analytes in extracts the spectrophotometric technique is used (as official regulation). For determination concentration of individual analytes were applied gas (derivatization step requires) and liquid chromatography mainly with mass spectrometry technique. The presence of anionic surface active agents was confirmed in various ecosystems (liquid and solid environmental samples).

“…Target compounds are isolated from the sample according to their relative solubilities in two different immiscible o partially miscible liquid phases, usually water and an organic solvent. Several cationic [20,65] and anionic compounds [78,79] have been extracted from aqueous samples using chloroform, whereas dichloromethane [80] and ethyl acetate [81] have been used to isolate non-ionic surfactants from water. The main advantage of LLE is that it can be used to determine total concentration of these compounds in water in spite of their solid particle matter level.…”

“…However, the tendency of surfactants to concentrate at phase boundaries leads to the formation of emulsions, and phase separation during LLE becomes very difficult. This can be avoided by the formation of liphopilic ion pairs between surfactants and ion-pair reagents [1] (e.g., disulphine blue dyes or LAS for cationic surfactants [65,77,82], methylene blue [78,79,83] or methylene green for anionic surfactants [84], modified Dragendorff reagent for non-ionic [81]). …”

“…The principal of this methodology is based on the formation of a chloroform extractable ion-association complex between the anionic or cationic surfactants and cationic (disulphine blue) or anionic (methylene blue) dyes, followed by a spectrophotometric measurement of the intensity of the extracted coloured complex as applied by Chitikela (1995), Oppo et al (1999), Latif and Brimblecombe (2004), Hanif et al (2009) and Roslan et al (2010).…”

Biomass burning contributes to various organic substances in the atmosphere. Levoglucosan has been recognised as one of the indicators of biomass burning and surfactants are a group of molecules which can be distributed through biomass burning. This research aims to determine the composition of levoglucosan and surfactants in agricultural areas and the several tropical plant species which can contribute to a high amount of levoglucosan and surfactants in the atmosphere. Suspended particulate matter in the atmosphere (fine and coarse mode) was collected in the agricultural areas (paddy fields) during the dry season and compared to samples collected at the Universiti Kebangsaan Malaysia (UKM), Bangi. The soot samples were prepared through the burning of several tropical plant species, namely: Oryza sativa, Rhizophora spp., Elaeis guineensis and Saccharum officinarum at 300°C in a furnace. This allowed for the levels of levoglucosan and surfactants such as MBAS and DBAS to be determined using the colorimetric method. Oxidation and UV radiation were also used to examine the impact of photo-oxidation on the concentration of levoglucosan and surfactants in soot. The results showed that the concentration of levoglucosan in the agricultural areas during harvesting season is significantly higher compared to the levoglucosan recorded at UKM Bangi (semi-urban areas). The concentration of surfactants is dominated by anionic surfactants, particularly in fine mode aerosols. Soot from leaves was found to contribute a high amount of levoglucosan when compared to wood and straw. There are indications that biomass burning can contribute to a large quantity of polar group molecules which behave like anionic surfactants and correlate to the amount of surfactants.
