Ethylhexyl Phthalate

The analysis of di-(2-ethylhexyl) phthalate (DEHP) was done in three kinds of polyethylene terephthalate (PET) plastic bottles of mineral water, namely: new bottle, ten times refilled and sunlight exposed new bottle. The optimal condition on this study is ethyl acetate as an organic solvent, 175 µl of organic solvent and 20 min of extraction time. This method has limit detection about 0.29 ppm, precision 96.48–110.10 %, accuracy until 1.95 % and enrichment factor until 302.67 times. Based on these results, cone shaped membrane-liquid phase microextraction method (CSM-LPME-HPLC) could be used to analyze DEHP in a PET plastic bottle of drinking water sample under mentioned kinds of circumstances with the concentration of 0.40, 0.53 and 0.76 ppm, respectively.
