Trace analysis of surfactants using chromatographic and electrophoretic techniques

摘要: Because of the widespread use, increased application new formulations and immense impact on organisms ecology surfactants are still in focus analytical chemistry. The development methods with higher selectivity lower detection limits is important to meet requirements greater responsibility for health people environment. Efficient separation methods, like HPLC, GC CE, combination sensitive detection, MS, be preferred over collective techniques which can suffer from interfering components. A review trace analysis ionic neutral including sample preparation steps presented, considering especially those provide information about homologous isomeric distribution surfactant mixtures. Examples determination linear alkylbenzene sulfonates river water by HPLC CE discussed show capability these environmental analyses. As future trends applications LC/MS (very high sensitivity) also (robustness possibility rapid method development) predicted.
