1. Introduction. Phthalate esters (PAEs) are nonplanar organic compounds with a fixed benzene ring and ortho-substituents. The widespread application of PAEs has led to their frequent occurrence and wide distribution in all environmental compartments, including drinking water, wastewater, sludge, dust, soil, sediment, and biota , .

Populus alba dioctyl phthalate uptake from contaminated water

Among PAEs, dioctyl phthalate (DOP) is a plasticizer, straight chain isomer of di-2-ethylhexyl phthalate (DEHP), with long alkyl ester chains and high hydrophobicity (DOP log K ow = 8.1). Its removal efficiency through WWTP is variable; in fact, the average DOP concentration ranges from 0.017 to 9.22 ppb in effluent waters, while 130 and 3461

Some of the phthalic acid esters with relatively high molecular weights, such as DEHP, DiNP, DiDP, dioctyl phthalate (DOP), and didecyl phthalate (DDP), are considered recalcitrant because the low water solubility of these phthalic acid esters could limit degradation (Ejlertsson et al., 1997, He et al., 2015).

Solid-phase microextraction (SPME) with a 100-µm polydimethylsiloxane (PDMS) fiber coupled to gas chromatography–mass spectrometry was used to determine 16 phthalate esters (PAEs) in wastewater from textile processing plants. Some of the 16 PAEs that exist as mixtures of isomers were identified and quantified.
