“…Analysis of compounds from the group of surfactants or their degradation products in environmental matrices is very complex and appropriate analytical techniques should be applied at sample preparation step and during separation, detection and quantification stages [67,68]. A lot of research has been done on the determination of non-ionic surface active agents and products of their metabolism in the aquatic and terrestrial ecosystems.…”

“…For ionization of non-ionic analytes were applied two techniques: atmospheric pressure chemical ionization (APCI) [26] and electrospray ionization ESI (has demonstrated higher sensitivity) [17,63]. The identification and quantitative analysis of non-ionic SAA was performed with the ion trap mass, quadrupole and triple-quadrupole mass spectrometers [64][65][66][67].…”

Non-ionic surface active agents are a diverse group of chemicals which have an uncharged polar head and a non-polar tail. They have different properties due to amphiphilic structure of their molecules. Commercial available non-ionic surfactants consist of the broadest spectrum of compounds in comparison with other types of such agents. Typically, non-ionic compounds found applications in households and industry during formulation of cleaning products, cosmetics, paints, preservative coatings, resins, textiles, pulp and paper, petroleum products or pesticides. Their are one of the most common use class of surfactants which can be potential pollution sources of the different compartment of environment (because of they widely application or discharging treated wastewaters to surface water and sludge in agricultural). It is important to investigate the behavior, environmental fate of non-ionic surfactants and their impact on living organisms (they are toxic and/or can disrupt endocrine functions). To solve such problems should be applied appropriated analytical tools. Sample preparation step is one of the most critical part of analytical procedures in determination of different compounds in environmental matrices. Traditional extraction techniques (LLE -for liquid samples; SLE -for solid samples) are time and solvent-consuming. Developments in this field result in improving isolation efficiency and decreasing solvent consumption (eg SPE and SPME -liquid samples or PLE, SFE and MAE -solid samples). At final determination step can be applied spectrophotometric technique, potentiometric titrametration or tensammetry (determination total concentration of non-ionic surfactants) or chromatographic techniques coupled with appropriated detection techniques (individual analytes). The literature data concerning the concentrations of non-ionic surfactants in the different compartments of the environment can give general view that various ecosystems are polluted by those compounds.

“…This technique requires use of organic solvent -chloroform and reagents to form hydrophobic ion pairs (eg disulphine blue dyes (DiSB), patent blue V, bromophenol blue, LAS [5,27]). Organic solvent allows for transfer ion pair of reagent-cationic surfactants from water to chloroform.…”

“…Sometimes during isolation of analytes from very complex matrixes interferences might be remove from sorbent with use appropriated solvents (mainly acetonitrile, water H 2 O). The cationic analytes are eluted for sorbent with use mixture of non-organic and organic solvents (acetonitrile, methanol, acetic acid, water, ammonium formate buffer) [27].…”

Abstract:Compounds from the group of cationic surfactants are widely applied in household, industrial, cleaning, disinfectant, cosmetic and pharmaceutical products as their specific properties (antimicrobial, emulsifying, anticorrosion, softening). After use, cationic surfactants are disposed to wastewater-treatment plants and finally with effluent water to surface waters due to their incomplete degradation. Moreover, they can freely circulate in different environmental compartments including living organisms. It becomes indispensable to recognize in more detail behavior, fate and biological effects of cationic surfactants. This analytical problem can be solved with use sensitive and reliable analytical techniques at sample preparation step and final determination step. In recent years, during isolation analytes from environmental samples mainly were used liquid-liquid extraction (LLE) -liquid matrices or solid-liquid extraction (SLE) -solid matrices. This technique involves application of toxic solvents (chloroform), is time-consuming and interferences are co-extracted. Nowadays, in scientific centers are carried out research to replace this traditional technique. So far, the following techniques were applied: solid-phase extraction (SPE) or it modification (HF-LPME) -liquid samples; accelerated solvent extraction (ASE) and supercritical fluid extraction (SFE) -solid samples. During the determination of total content of cationic surface active agents in environmental samples were used a traditional spectrophotometry technique and potentiometric titration technique. But those techniques are susceptible of interferences on analysis results (anionic and non-ionic compounds). The chromatographic technique (liquid chromatography) applied at the final determination step gives possibility to determine individual cationic surfactants in solvent extracts of environmental samples. The LC systems coupled with mass spectrometers are most powerful tools during such analysis.
