Summary: This review summarizes the physicochemical characteristics of microplastics (MPs) undergoing natural and artificial aging and evaluates current analytical methods used in aging studies. It discusses the differences in photoaging and aging induced by advanced oxidation processes (AOPs) and highlights the environmental behavior and adsorption properties of aged MPs. The mechanisms of photoaging and AOPs-initiated aging are also analyzed, along with the applications of 2D-COS and EEM-PARAFAC for aging process analysis.

Summary: In this study, a novel polymerized polyaluminum-titanium chloride composite coagulant (PATC) was prepared and used to remove polystyrene (PS). PATC was found to compress or destroy the surface layer of negatively charged PS, leading to a more efficient removal of PS particles compared to other coagulants. The interaction between PATC and PS was mainly polar interaction, such as hydrogen bonding. This study provides systematic knowledge for understanding the interaction between PS, NOM, and coagulant hydrolysates, and confirms the application potential of PATC for MPs removal.

Summary: This study investigated the polymeric species and coagulation behavior of microplastics (MPs) and nanoplastics (NPs) influenced by the iron content in polymeric Al-Fe coagulants. The results showed that iron weakened the removal of NPs but enhanced the removal of MPs. This study provides a better coagulant option for removing micro/nanoplastics and minimizing aluminum residue, with promising potential for water purification applications.

Summary: Microplastics (MPs) are contaminants produced during the use and disposal of plastic products, posing a significant threat to human health. Efficient methods for removing MPs from water and wastewater treatment processes, such as membrane filtration, adsorption, coagulation-flocculation-sedimentation, bioremediation, and advanced oxidation processes, have been systematically discussed in this article. The characteristics, mechanisms, advantages, and disadvantages of these methods are highlighted. Future trends and challenges in the remediation of MPs are also proposed to achieve a more efficient, scalable, and environmentally-friendly approach.

Summary: Most studies on the interaction between coagulation and natural organic matter (NOM) focus on pollutant removal and coagulant species distribution, neglecting the study of floc aging. This study investigates the effects of aging on flocs generated by different coagulants and demonstrates that flocs absorb and release organic matter during aging. The type of coagulant and presence of nanoparticles affect the absorption and release patterns of organic matter.

Summary: This study systematically investigated the interaction between polystyrene nanoplastics (PSNPs) and Al2O3 under different conditions. It was found that significant heteroaggregation occurred between PSNPs and Al2O3 under acidic and neutral conditions. The NaCl concentration and pH values influenced the deposition of PSNPs on Al2O3 surfaces. Humic acid and fulvic acid prevented the deposition of PSNPs, with humic acid being more effective. The research provides insights into the migration and fate of PSNPs in aquatic environments.

Summary: In this study, a series of Al-Ti gels with different Ti/TEA, Ti/H2O, and Ti/Al ratios were prepared by sol-gel process. The interaction mechanism between Al and Ti was explored, and the most efficient Al-Ti gel was applied to lake water treatment. The results showed that Al-Ti gel had higher removal efficiency for organic matter compared to Ti gel, providing theoretical guidance for the study of the interaction mechanism between Al and Ti in composite coagulants and actual water treatment.

Summary: The hydrolysate species of metal-based coagulants and the binding sites of humic acid are highly dependent on the pH conditions. The study found that oligomeric and mesopolymeric hydrolysates were the dominant species under acid conditions and could complex with the hydroxyl and carboxyl groups of humic acid. With the increase of pH, the hydrolysis process of the coagulant and the deprotonation of humic acid were simultaneously underway. Under weakly acid conditions, the complexation of the aluminum hydrolysates with carboxyl groups was improved. Under alkaline conditions, the sweeping effect of amorphous hydroxide dominated the humic acid removals.

Summary: The study found that prehydrolyzed coagulants containing polymeric and/or cationic aluminum species are more effective in removing organic matter from water sources compared to conventional metal salt coagulants. In acidic conditions, ferric sulfate outperformed aluminum-based coagulants, while aluminum chlorohydrate was repeatedly noted as the best option in more alkaline conditions. Alum offered a good compromise between DOC and turbidity removals in neutral pH range.

Summary: This study investigated the performance of anionic polyacrylamide (PAM), sodium alginate (SA), and activated silicic acid (ASA) in enhancing the removal of polyethylene terephthalate (PET) microplastics using poly-aluminum chloride (PAC). The results showed that ASA had the highest removal efficiency at conventional dosage, while PAM achieved the best removal effect at high dosage. The mechanism of coagulation was studied, and increasing the dosage of coagulant aids significantly improved the effect of adsorption and sweep flocculation. Additionally, jar tests demonstrated that the current coagulation systems were highly adaptable.

Summary: The study investigated the coagulation mechanism for removing humic acid (HA) using Al-13 and optimized its operation. Results showed that preformed Al(13)agg performed better than Al-13 in removing HA, due to its wider pH range and lower residual aluminum levels. The different coagulation mechanisms for Al-13 and Al(13)agg played roles in HA removal, with complexation and charge neutralization dominating for Al-13 and sweep flocculation and adsorption coagulation being the main driving forces for Al(13)agg.
