“…Cross-peaks appeared at 1150, 1437, 1525, 564, and 1056 cm −1 in the asynchronous map, and there were different phases between the dynamic spectral intensity changes in the two wave numbers. These peaks on a nondiagonal line were positively–negatively correlated [ 39 , 40 ]. The characteristics of autocorrelation and cross-correlation peaks in synchronous and asynchronous two-dimensional correlation spectra could be explained by Noda rules.…”

Selective phosphorus removal from aquatic media has become an ideal strategy to mitigate eutrophication and meet increasingly stringent discharge requirements. To achieve phosphorus control and resource utilization of low-calorific-value lignite, iron and magnesium salts were used to functionalize lignite, and iron–magnesium functionalized lignite (called IM@BC) was prepared for phosphate recovery from water media. The adsorption properties of IM@BC were systematically evaluated, especially the influence of ambient pH and co-existing ions. The kinetic, isothermal, and thermodynamic adsorption behaviors of IM@BC were analyzed. The adsorption mechanism was revealed by microscopic characterization. The potential application of phosphate-containing IM@BC (P-IM@BC) was explored. The results show that IM@BC has a strong phosphate adsorption capacity, and the maximum adsorption capacity is 226.22 mgP/g at pH = 3. Co-existing CO32− inhibits phosphate adsorption, while coexisting Ca2+ and Mg2+ enhance the effect. At the initial adsorption stage, the amount of phosphate adsorbed by IM@BC continues to increase, and the adsorption equilibrium state is gradually reached after 24 h. The adsorption process conforms to the pseudo-second-order kinetic model (PSO) and Langmuir isothermal adsorption model, and the adsorption process is mainly chemical adsorption. The phosphate absorption capacity is positively correlated with temperature (283.15 K~313.15 K), and the adsorption process is spontaneous, endothermic, and entropy-increasing. Its adsorption mechanism includes electrostatic attraction, ion exchange, surface precipitation, and coordination exchange. IM@BC can efficiently recover phosphate from actual phosphorus-containing wastewater with a recovery efficiency of up to 90%. P-IM@BC slowly releases phosphate from pH 3 to 11. Plant growth experiments showed that P-IM@BC could be used as a slow-release fertilizer to promote the root growth of cowpeas. The novelty of this work lies in the development of a highly efficient phosphate recovery adsorbent, which provides a feasible method of phosphorus control in water media and resource utilization of lignite.

“… 29 − 32 In addition, it has also recently been confirmed that the antibiotic sorption capacity of micro(nano)plastics affects the further biological activity of the surfaces, e.g., biofilm attachment/production ability. 33 Furthermore, the sorption of antibiotics onto micro(nano)plastics can cause another issue for the environment and human health, bacterial resistance. The sorption of antibiotics from the surrounding environment and selective colonization/enrichment of antibiotic-resistant bacteria on plastic particles exhibit favorable conditions for higher transmission and propagation of antibiotic-resistance.…”

“…In recent years, various laboratory-based studies approved the sorption of antibiotics onto microplastics. The antibiotic sorption properties onto plastic particles are considered to depend on the plastic particles’ surface chemistry, and various sorption pathways were described for the interaction of plastic particles with antibiotics, namely, the van der Waals force, hydrophobic interaction, electrostatic interaction, hydrogen bonding, partitioning, micropore-filling mechanism, π–π interaction, and charge-assisted hydrogen. − In addition, it has also recently been confirmed that the antibiotic sorption capacity of micro(nano)plastics affects the further biological activity of the surfaces, e.g., biofilm attachment/production ability .

Recent studies have shown that plastic particles can sorb antibiotics, and these sorption properties have been examined in various studies; however, the possible mechanism responsible for the interactions requires a deeper investigation in terms of further interaction with living systems. Moreover, the usage of disposable surgical masks and plastic bottles has increased the plastic pollution risk for living systems like humans. Therefore, this study aimed to examine the sorption characteristics between antibiotics (amoxicillin and spiramycin) and plastic particles from surgical masks and plastic bottles through batch sorption experiments. In the study, their surface interactions were characterized using multispectroscopic approaches including FTIR, Raman spectrometry, and SEM-EDX, and various surface indicators (e.g., surface oxidation, deformation, and biological potential) were examined. The sorption results showed that adsorption kinetics and the isotherm of amoxicillin and spiramycin on micro(nano)plastics from surgical masks and plastic bottles closely fit the pseudo-second-order kinetic model and Langmiur isotherm. These results indicated that the evidence for the antibiotic interaction with particles was changes in the surface functional group intensities and up-shifting, and this correlated with the sorption of antibiotics on micro(nano)-sized plastics. The C/N ratio of the plastic particles before and after antibiotic treatment was used as an indicator for the surface biological interaction, and the results showed that C/N ratios of surgical mask particles increased with both types of antibiotic sorption. However, the C/N of the particles from plastic bottles showed antibiotic type-dependence. The surface deformation indicators (e.g., O/C, CO, CC, and O–H indices) showed that the O/C ratios of micro(nano)plastics from surgical masks were higher with the amoxicillin and spiramycin sorption, and the CO indices were positively linked with the amoxicillin sorption stages, whereas the CC and O–H had a negative correlation with the amoxicillin sorption stages. Moreover, amoxicillin sorption influenced the O/C ratio and indices of O–H and CC of micro(nano)plastics from plastic bottles in a limited manner. The CO groups of the micro(nano)plastics from plastic bottles were positively influenced by the spiramycin sorption stages, whereas it was negatively linked with amoxicillin sorption stages. Overall, the findings from surface indicators indicated that the micro(nano)plastics from surgical masks can be more influenced with antibiotic sorption compared to plastic bottles.
