| Popis: | Five methods have been successfully developed which are the ionic liquid–two-phase extraction (IL-ATPS), ionic liquid–two-phase extraction with addition of β-cyclodextrin as modifier (IL-βCD-ATPS), cloud point extraction (CPE-DC193C), cloud point extraction with addition of β-cyclodextrin as modifier (CPE-DC193C-βCD), and cloud point extraction with addition of ionic liquid functionalized β-cyclodextrin as modifier (CPE-DC193C-βCD-IL). These methods are new, green, and simple extraction technique to couple with a reversed-phase high-performance liquid chromatography to get the optimum conditions for phase separation of parabens in water samples. The parameters, i.e. pH of the solution, water content, distribution coefficient, and preconcentration factor, are evaluated to get the optimum conditions for phase separation of parabens. The CPE-DC193C-βCD-IL method shows the highest losses of water content among other methods. It also produces the highest preconcentration factor and distribution coeffic... |
