Abstract

Recently, a new group of compounds, namely Switchable hydrophilicity solvents, has been introduced into the extraction field. In this study, a pH assisted homogeneous liquid-liquid microextraction method based on Switchable hydrophilicity solvents followed by GC-MS detection has been developed for preconcentration and determination of Polycyclic aromatic hydrocarbons (PAHs) in water samples. The extraction method includes two steps. In the first step, the waterimmiscible solvent (N, N-Dipropylamine) is dissolved in the aqueous phase using hydrochloric acid as a reagent. Afterwards, the separation of organic and aqueous phases is accomplished by the addition of sodium hydroxide. The effects of experimental parameters of the extraction such as temperature, time, the volume of acceptor phase, pH of donor phase, and ionic strength of solution were investigated. Under the optimum conditions, the proposed method provided good linearity in the range of 2– 1000 μ g L− 1 for anthracene and pyrene and 4-1000 μ g L− 1 for naphthalene. Also, limit of detection for anthracene and pyrene was 0. 6 μ g L− 1 and for naphthalene was 1. 21 μ g L− 1. Extraction repeatabilities were obtained as RSD% in the range of 4. 3-6. 8. Finally, the application of the proposed method for the analysis of target analytes in different water samples was successfully investigated.
