“… Notably, the theoretical adsorption amounts for TOB ( Q m2 = 223.2 mg g –1 ) and OFLX ( Q m2 = 118.3 mg g –1 ) calculated by the pseudo-second-order model was closer to the actual saturated adsorption amount ( Q e = 231.1 mg g –1 and 140.8 mg g –1 ), and R 2 was closer to 1 (Table S2). Its outstanding adsorption amounts was higher than those of reported porous adsorbents (Table S3), such as CMIPs (19.72 mg g –1 ), Fe 3 O 4 @poly (12.6 mg g –1 ), SiO 2 @PVA/Gel (7.12 mg g –1 ), DMIPs (128 mg g –1 ), DES-MUiO-66-NH 2 (97.6 mg g –1 ), activated carbon (132 mg g –1 ), BNNSs (72.5 mg g –1 ), and NBC (54.05 mg g –1 ) . It should be attributed to the structural advantage of the carboxyl group, which induces much faster and more cooperative binding than other adsorbents without functionalized groups.…”

The effective removal of hydrophilic pollutants is of vital significance for environmental protection mainly because of the low efficiency of traditional sewage treatment methods. In this work, the cyano-vinylene-linked covalent organic polymer was prepared using 2,2′,2′′-(benzene-1,3,5-triyl)triacetonitrile (BTNA) and 2,4,6tris(4-formylphenyl)-1,3,5-triazine (TFPT) as the Knoevenagel reaction monomers. The cyano group was then hydrolyzed to obtain a carboxyl-functionalized covalent organic polymer (COP-COOH). With good surface area (73.9 m 2 g −1 ) and large channel (∼3.82 nm), TFPT-BTAN-COP-COOH showed fast adsorption equilibrium and high adsorption capacity for tobramycin and ofloxacin via multiple-functional binding sites. Specifically, the electrostatic interaction between the carboxyl group and basic groups (e.g., amino, piperazine, and dihydropyridine) plays a critical role for the selective removal of tobramycin and ofloxacin. The binding energies of TFPT-BTAN-COP-COOH adsorbed tobramycin and ofloxacin calculated using the density functional theory are −59.83 and −35.63 kcal/mol, respectively. For other aminoglycoside and quinolone antibiotics, such as enrofloxacin, norfloxacin, neomycin, and streptomycin, the removal rate can reach over 95% within 30 min using TFPT-BTAN-COP-COOH as the adsorbent. This work explored a promising strategy for the elimination of hydrophilic organic pollutants during environmental remediation.

“…Changing to a solvent with a low swelling degree will make the material shrink, conducive to elution. 52 Therefore, the swelling characteristics of the adsorbent in three different solvents (H 2 O, MeOH and ACN) were investigated and are shown in Table S5. † Compared to MeOH or ACN, two adsorbents (SiO 2 @PVA and SiO 2 @PVA/HA) exhibited significant swelling ratios in H 2 O.…”

“…Polyvinyl alcohol (PVA) is a synthetic biocompatible polymeric material that is highly hydrophilic, film-forming, inexpensive and chemically stable. 52 Although PVA is biodegradable, it would be more significant to use waste PVA as a raw material to achieve secondary high value-added applications compared to degradation methods. 53 PVA has a unique chemical structure and good recyclability, and the combination of waste PVA with HA is expected to solve the related problems of HA as an adsorbent.…”

An ultra-high-performance liquid chromatography-tandem mass spectrometry method was developed for simultaneous determination of 10 kinds of aminoglycosides in edible parts of aquatic products. The samples were extracted with 10 mmol/L potassium dihydrogen phosphate buffer solution, then the pH value of the extract was adjusted to neutral by sodium hydroxide. Half volume of the extract was loaded onto multiwalled carbon nanotubes cartridge. All the target compounds were separated on a mixed-mode ion exchange column and detected by ultra-high-performance liquid chromatography-tandem mass spectrometry with electrospray in the positive ionization mode. Under optimized conditions, this method had a good linearity with a squared correlation coefficient > 0.999. For neomycin, the limit of detection and limit of quantification were 5.0 μg/kg and 10.0 μg/kg, respectively; for hygromycin B and apramycin, values were 2.0 μg/kg and 5.0 μg/kg, respectively; for the other seven kinds of aminoglycosides, values were 1.0 μg/kg and 2.0 μg/kg, respectively. The average recoveries presented 75.8%-107.2% with intra-and interday reproducibility ranging between 3.8% and 12.5%. The method was rapid with good separation and sharp peak shapes, had the characteristicsis of high accuracy and good precision, and was suitable for simultaneous determination of 10 kinds of aminoglycosides in aquatic products.
