A simple and rapid magnetic solid-phase extraction based on reduced graphene oxide/ferroferic oxide (rGO/Fe3O4) coupled with high performance liquid chromatography-diode array detector (HPLC-DAD), was proposed for the determination of naproxen and diclofenac sodium of non-steroidal anti-inflammatory drugs (NSAIDs) and bisphenol-A residue in tap water sample. Fe3O4 was assembled with graphene oxide by facile method. Several important parameters, such as extraction time, desorption time and desorption solvent were studied and optimized. Optimal conditions were then used for the extraction of NSAIDs and bisphenol-A from real samples, prior to HPLC-DAD analysis using C18 column. The proposed method provides good linearity in the range of 1.0-5.0 mg L-1 (R2 naproxene = 0.9983, R2 diclofenac = 0.9960) for NSAIDs and R2 = 0.9919 for bisphenol-A; limit of detection of 0.031 mg L-1 and 0.023 mg L-1 for naproxen and diclofenac, respectively and 0.1785 mg L-1 for bisphenol-A; limit of quantification for naproxen and diclofenac were 0.102 and 0.076 mg L-1, respectively and 0.5949 mg L-1 for bisphenol-A; relative recoveries between 66.21 and 105.60 % for diclofenac and naproxen, respectively and 72.74 % for bisphenol-A; and acceptable reproducibility relative standard deviation (RSD, n = 3) of 6.79 and 11.32 % for diclofenac and naproxen, respectively and 0.93 % for bisphenol-A. The method was successfully applied to tap water sample and the results indicates that small residue of bisphenol-A is present the sample while no traces of NSAIDs was detected.

Calixarene framework functionalized bio-polymeric magnetic composites (MSp-TDI-calix) were synthesized and utilized as magnetic solid-phase extraction (MSPE) sorbent for the extraction of non-steroidal anti-inflammatory drugs (NSAIDs), namely indoprofen (INP), ketoprofen (KTP), ibuprofen (IBP) and fenoprofen (FNP), from environmental water samples. MSp-TDI-calix was characterized by FT-IR, XRD, FESEM, EDX, VSM and BET analysis, and the results were compared with Sp-TDI and Sp-TDI-calix. To maximize the extraction performance of MSp-TDI-calix decisive MSPE affective parameters such as sorbent amount, extraction time, sample volume, type of organic eluent, volume of organic eluent, desorption time and pH were comprehensively optimized prior to HPLC-DAD determination. The analytical validity of the proposed MSPE method was evaluated under optimized conditions and the following figures of merit were acquired: linearity with good determination coefficient (R2 ≥ 0.991) over the concentration range of 0.5–500 µg/L, limits of detection (LODs) ranged from 0.06–0.26 µg/L and limits of quantitation (LOQ) between 0.20–0.89 µg/L. Excellent reproducibility and repeatability under harsh environment with inter-day and intra-day relative standard deviations were obtained in the range of 2.5–3.2% and 2.4–3.9% respectively. The proposed method was successfully applied for analysis of NSAIDs in tap water, drinking water and river water with recovery efficiency ranging from 88.1–115.8% with %RSD of 1.6–4.6%.

A magnetic solid-phase extraction (MSPE) procedure on the newly synthesized magnetic β-cyclodextrin functionalized with toluene diisocyanate (TDI) as a linker and further modified with bio-polymeric spores of sporopollenin (MSp-TDI-βCD), was developed for the extraction of nonsteroidal anti-inflammatory drugs (NSAIDs), namely, indoprofen (INP), ketoprofen (KTP), ibuprofen (IBP) and fenoprofen (FNP) from water samples prior to their HPLC-DAD determination. The newly synthesized MSp-TDI-βCD was comprehensibly characterized using FT-IR, XRD, SEM-EDX, BET and VSM analyses. The separation of selected NSAIDs on MSp-TDI-βCD from aqueous solution was simply achieved by applying an external magnetic field via a permanent magnet. The MSPE parameters affecting extraction performance, i.e. sorbent dosage, sample volume, extraction and desorption time, type of organic eluent and volume and solution pH were investigated and optimized. The proposed method showed linear range between 0.5 and 500 ng ml −1 , low limit of detection at S/N = 3 (0.16–0.37 ng ml −1 ) and limit of quantification at S/N = 10 (0.53–1.22 ng ml −1 ). The inter-day ( n =  15) and intra-day ( n =  5) precision for the proposed methods given by relative standard deviation (RSD%) was in the range of 2.5–4.0 and 2.1–5.5, respectively. The extraction recoveries of NSAIDs from environmental samples (tap, drinking and river water) ranged from 92.5% to 123.6%, with satisfactory precision (RSD% less than 12.4%).
