Extraction of Phthalic Acid Esters and Di(2-ethylhexyl) Adipate from Tap and Waste Water Samples Using Chromabond® HLB as Sorbent Prior to Gas Chromatography-Mass Spectrometry Analysis

“…Although, the recovery values of those three analytes (DPP, BBP, and DCHP) were out of the 70-120% range at one of the concentration levels and samples, the mean values of all levels were in the acceptable range 70-120% and always with RSD values below 20% [30]. Such recovery values are also similar to the ones reported by previous works in which Oasis ® HLB cartridges were used for the extraction of some of these analytes from water samples [16,18,19] except for DIPP, DNPP, and DCHP, which were not analyzed in those cases. Such data, which can be seen in Supplementary Materials Table S2, suggests that Chromabond ® HLB stationary phase can perfectly be used as substitute of Oasis ® HLB for the extraction of the selected PAEs and DEHA from tap and waste water samples.…”

“…Supplementary Materials Table S2 shows a comparison among different previous works in which Oasis ® HLB cartridges have been applied for the extraction of PAEs and/or DEHA from water samples. In general, more complicated and longer extraction procedures were carried out, using several solvents for the sorbent activation as well as the elution of the analytes, even making use of chlorinated solvents in some cases [17][18][19][20]. As can be seen, the methodology proposed in this work presents in many cases a simpler and faster alternative for the extraction of PAEs from water samples, maintaining an excellent extraction efficiency and, in most cases, a comparable sensitivity, despite a much lower volume of sample is analyzed compared to the works previously published using this kind of sorbent.…”

“…The particles' size of commercialized sorbents is also variable: 5, 15, 25, 30, and 60 µm [13]. These types of cartridges have been applied in several works for the extraction of diverse groups of PAEs from different water samples with success [14][15][16][17][18][19][20].…”

Gc-Fid Based Analysis of Trace Phthalates with a Novel Nanocomposite by Polar-Nonpolar Properties in Plastic Bottled Water

“…Therefore, proposing a method for trace determination of phthalates could be interested in these years. To determine low concentration of phthalates, various solid phases have been suggested, including microsphere, polyaniline coated chitosan nanocomposite, poly m-aminophenol /nylon 6/graphene oxide and ZIF-8 in different samples [13][14][15][16]. However a potent sample preparation for phthalate extraction are needed.…”
