“…The patulin removal efficiency increased from 76.71% to 98.08% as the temperature increased, which meant that temperature played an important role in the patulin adsorption process by the SH‐membrane adsorber. This result proved that the adsorption of patulin onto SH‐membrane adsorber was an endothermic process, a similar result was observed by other researchers …”

“…While the removal efficiency of nylon membrane, PDA/nylon membrane and PEI‐PDA/nylon membrane was about 7.98%, 8.87%, and 65.24%, respectively. The possible reason was that patulin could be covalently bonded by thiol or amine group through Michel addition reaction, and the activity of thiol group was higher than that of amine group, as reported in the previous literature …”

“…Anene et al developed a molecularly imprinted polymer material to capture patulin through selective cavity . But these weak interactions were easy to cause patulin escaping, so some researchers further fabricated thiol‐modified material to remove patulin through Michael addition reaction between patulin and thiol groups . However, how to regenerate and recover these functionalized polymers is another challenging work.…”

The ORCID identification number(s) for the author(s) of this article can be found under https://doi.org/10.1002/mame.201800790. Membrane AdsorberMussel-inspired membrane adsorber with thiol ligand (SH-membrane adsorber) is prepared by polydopamine-assisted poly(ethylene imine) grafting and subsequent thiolation modification for efficient removal of patulin. The effects of temperature, contact time, pH, and initial patulin concentration on the adsorption capacity of the membrane adsorber are investigated. The results show that the SH-membrane adsorber is effective to remove patulin. The adsorption capacity of the membrane can reach 1245.11 µg g −1 for patulin. In static adsorption tests, the adsorption kinetic and equilibrium data are well fitted by the pseudo-second-order kinetic model and Freundlich isotherm model, respectively, meaning that the adsorption process is a multilayer chemical adsorption. The SH-membrane adsorber can be recovered by l-cysteine, and the removal efficiency of patulin is maintained at about 89.23% after eight reuse cycles, compared to the 17.33% of control membrane. These results demonstrate that the SH-membrane adsorber has a potential application for patulin removal.

“…Accordingly, it was deduced that such adsorption is endothermic in nature. The same trend, the increase significantly in the adsorption efficiency with the increase in temperature, was observed for the sorption of patulin onto thiourea modified chitosan resin (Liu et al, ).…”

“…In many countries, the patulin levels in the final juice product have been suggested as an indicator of the original fruit quality (Liu et al, ). However, a considerable amount of apple juices existing at various markets exceed the maximum recommended concentration of 50 μg/L of patulin, which raises serious concerns about the food safety of apple products (Zouaoui, Sbaii, Bacha, & Abid‐Essefi, ).…”

This study investigated water-insoluble corn flour (WICF) as a novel biosorbent for removing patulin from aqueous solutions, including contaminated fruit juices. Batch adsorption experiments were performed to assess the effect of granularity of WICF, adsorbent dosage, contact time, temperature, pH, and initial patulin concentration. The results showed that the maximum removal percentage of 92.21% was achieved at 37 8C, pH value of 4.0 in 100 mg/L patulin concentration for 25 hr. The adsorption data could be well fitted with the Freundlich isotherm model and the pseudo-first order model. Thermodynamic parameters indicated that mycotoxin adsorption is an endothermic and spontaneous process. Subsequently, scanning electron microscopy images showed obvious morphological changes in WICF after adsorbing patulin. Fourier transform infrared spectroscopy spectroscopic evidence demonstrated that the main functional groups involved in the adsorption were O-H, C 5 O and C-O groups. Practical applicationsPatulin was found as a contaminant in various fruit juices, which raised serious concerns about developing an effective and cheap adsorbent for detoxification of patulin toxin in fruit juice and their products. Water-insoluble corn flour was applied to strengthen the control of patulin for the first time. Results of this study indicated that water-insoluble corn flour has a strong ability to remove patulin from aqueous solutions and various fruit juices. Therefore, using water-insoluble corn flour as an adsorbent and combining the filtration process could be potentially applied in fruit juice industry for detoxification of patulin.

Ethyl carbamate (EC) is a kind of genotoxic and carcinogenic substance and potentially harmful to human health. In this study, simple and effective removal of EC from liquor samples by using the magnetic mesoporous adsorbent (Fe3O4@COFs) was investigated. Gas chromatography and triple quadrupole tandem mass spectrometry (GC‐MS/MS) was used to monitor the whole of adsorption process. The results showed that the adsorbent has high efficiency and fast adsorption capacity. Under the optimized adsorption parameters, pseudo‐first‐order and pseudo‐second‐order kinetic models were employed to reveal the underlying sorption mechanism. Results indicated that the adsorption of EC on Fe3O4@COFs is more consistent with the pseudo‐second‐order model. Furthermore, an effective method for the adsorption and detection of EC was successfully developed, which exhibited good linearity with R2 ranging from 0.9954 to 0.9998, satisfactory recoveries in the range of 86.9%–116.2%, and the relative standard deviations (RSD) was lower than 5.8%. Fe3O4@COFs showed good stability and excellent performance in removing EC from liquor samples. It is expected that the proposed magnetic COFs hold great promise for liquor sample pretreatment and be extended for application in other fields.
