A new polyurethane adhesive was evaluated to fix a hydrophilic-lipophilic-balanced sorbent and to produce modified stir-bars. It presented high mechanical and chemical resistance, indicating that it is an adequate adhesive. The homemade bars were employed to determine bisphenol A, diclofenac, ibuprofen and triclosan in aqueous medium. Satisfactory figures of merit were observed, with LOD between 0.06 and 0.30 ng mL-1 and enrichment factors between 133 and 195 times, using an extraction time of 2 h. The stir-bars were employed to determine the four analytes in water samples, presenting recovery results from 53 to 135% and RSD between 0.7 and 20%. In general, the results observed here indicated that the adhesive is an appropriate alternative material to fix HLB particles, and could probably be applied to other sorbents.
