“…The practical implementation of such strict control requires, however, an expeditious and cheap analytical method, capable of providing analytical data in real time (or near), on-site. Different works have been described for sulphonamide determination, most of which employing chromatographic systems with UV/vis [18][19][20][21][22][23][24] or mass spectrometry [25][26][27][28][29] detection schemes. These are typically unable to fulfil the basic requirements of this strict control.…”

This work develops a simple and innovative test-strip to monitor antibiotics in aquaculture facilities by an equipment-free approach. It consists of a low-cost disposable cellulose paper that was chemically modified to produce a colour change when in contact with a given antibiotic. In brief, the cellulose substrate was subject to oxidation with periodate, followed by amination with chitosan binding and modification with Cu(II). The test strip was then dipped in the target solution and the intensity of the colour generated therein revealed the concentration of antibiotic present for concentrations higher than 0.5 mM. The higher the concentration in sulfadiazine (SDZ), the more intense the pink colour formed in the final solution, which was also turbid due to the insolubility of the formed product. This colour intensity also varied linearly with the logarithm of the SDZ concentration (from 0.5 to 5 mM), when plotted against the sum of the RGB coordinates extracted from digital pictures. The linear equation of this response was represented by (R + G + B) = − 256.1 log(SDZ, mol/L) − 362.0, with an R-squared of 0.9913. The test-strip was stable for at least 15 days and was selective in the presence of tetracycline and difloxacin, while the response to other members of the sulfadiazine family requires prior evaluation. Overall, the test-strips developed herein are inexpensive and provide valuable (semi-) quantitative data for monitoring SDZ in waters, a most valuable approach to control and reduce the level of antibiotics in fish tanks, which in turn may reduce the costs of fish production and the environmental concerns linked to this practice. Moreover, the test strip uses a cellulose substrate that has little environmental impact upon discard.

“…For water-stable MOFs, such as MIL-101, ZIF-8, and ZIF-67, they are promising candidate SPE sorbents. Dai et al [44] explored MIL-101(Cr) packed SPE column to enrich SAs from aqueous matrix. The existence of metal sites, carboxyl rings, and phenyl rings of MOFs offers various coordination bonds, intermolecular hydrogen bonds, π-π stacking, and hydrophobic forces with SAs, respectively, which promote the adsorption of SAs on the surface of MIL-101(Cr).…”

Metal-organic frameworks are promising materials in diverse analytical applications especially in sample pretreatment by virtue of their diverse structure topology, tunable pore size, permanent nanoscale porosity, high surface area, and good thermostability. According to hydrostability, metal-organic frameworks are divided into moisture-sensitive and water-stable types. In the actual applications, both kinds of metal-organic frameworks are usually engineered into hybrid composites containing magnetite, silicon dioxide, graphene, or directly carbonized to metal-organic frameworks derived carbon. These metal-organic frameworks based materials show good extraction performance to environmental pollutants. This review provides a critical overview of the applications of metal-organic frameworks and their composites in sample pretreatment modes, that is, solid-phase extraction, magnetic solidphase extraction, micro-solid-phase extraction, solid-phase microextraction, and stir bar solid extraction.

“…35,36 Moreover, MIL-101(Cr) was employed as adsorbents for solid phase extraction (SPE) for the determination of sulphonamides in environmental water samples coupling with UPLC-MS/MS. 37 A core-shell MIPs coated onto the surface of MIL-101(Cr) was prepared, which was used as absorbents for the detection of pyrraline in milk and milk powder. 38 NH 2 -MIL-101(Cr) was synthesized via a direct hydrothermal method and was coated with polydimethylsiloxane and stir bar for the determination of organophosphorus pesticides in environmental water samples.…”
