The speciation, mobility, and fate of Sb in the environment are intricately linked to its interactions with iron minerals at micro-interfaces. This study investigated the immobilization behavior and mechanisms of Sb(III) and Sb(V) at relatively high environmental concentrations onto schwertmannite (Sch), a common iron mineral prevalent in mining areas, with ferrihydrite (Fh) serving as a reference. Batch adsorption experiments demonstrated that Sb(V) adsorption was favored at low pH, whereas Sb(III) adsorption increased significantly at higher pH levels. The maximum adsorption capacities of Sch for Sb(V) and Sb(III) was determined to be 100.8 mg/g and 111.1 mg/g, respectively, at pH 7.0. Sequential extraction and spectroscopic analyses revealed that Sb immobilization on Sch occurred through hydroxyl complexation, structural incorporation, and surface precipitation mechanisms, with sulfate exchange also contributing to the immobilization of Sb(V). Additionally, Sb adsorption increased the mineral stability, enhancing the resistance to acidic dissolution. The co-existing As influenced Sb adsorption, with As(III) exerting a stronger inhibitory effect on Sb(III) adsorption. These findings reveal the immobilization behavior and mechanisms of high-concentration Sb by Sch, emphasizing the critical roles of structural incorporation and surface precipitation in Sb immobilization.

The flocculation process was assessed by measuring the percentage removal of physical and chemical water quality parameters. Empirical equations were used to optimize these parameters. The NS/AS mixture exhibited good flocculant capacity under acidic conditions, achieving significant removal of color, conductivity, turbidity, total dissolved solids (TDS), chemical oxygen demand (COD), total organic carbon (TOC), and nitrites. However, its removal efficiency for biological oxygen demand (BOD₅) and phosphates was lower. Optimization results identified ideal conditions as 30 mg·L⁻¹ of NS, 20 mg·L⁻¹ of AS, a pH of 5.5, and an agitation speed of 100 rpm (RPM), achieving up to 50.17 % turbidity removal.

The efficacy of EKR-PRB is significantly influenced by the choice of reactive materials. This paper provided beneficial insights into EKR-PRB, highlighting their fundamental mechanisms, definitions, and principles.

This research focused on evaluating the effectiveness of permeable reactive barrier (PRB) by analyzing their durability, mechanisms of contaminant removal, and structural design within the context of electrokinetic remediation (EKR). Five installation configurations were assessed to determine optimal placement for different pollutant types, with specific setups enhancing removal efficiency significantly. Cost and scalability were analyzed further, revealing that while EKR-PRB are promising for various low-permeability soils, challenges in engineering applications remain due to soil heterogeneity, changes in pH, and limited electroosmotic flow.

To verify these theories, statistical and block copolymers with various compositions (0, 30, 50, 70, 100 mol.%) of acryloyl pyrrolidine (APy) with acryloyl piperidine (APi) were synthesized and sI methane hydrate growth kinetics were measured at 2 °C and 4646 kPa. All tested KHI samples reduced methane consumption to <25 % of that of an uninhibited system. Poly(APi) with bigger amide rings and lower CPT acted as a poorer KHI than the more hydrophilic poly(APy). The statistical copolymers with a wide range of CPTs from 4 to 48 °C showed that KHI performance was not influenced by CPT, as the sI hydrate growth rate exhibited a nearly linear relationship with respect to copolymer composition. On the other hand, results of block copolymers suggest that the thermoresponsive behavior of these surfactant-like additives might play a role during hydrate growth inhibition. The block copolymer with 30 mol.% APi acted as the best KHI amongst all tested samples, while the block copolymer with 70 mol.% APi acted as the poorest. The results were significantly different from the statistical copolymers with similar composition; thus, copolymer microstructure is also a factor to consider during KHI design.</div></div>","PeriodicalId":9749,"journal":{"name":"Chemical Engineering Journal Advances","volume":"23 ","pages":"Article 100770"},"PeriodicalIF":5.5,"publicationDate":"2025-05-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144071826","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This drawback severely limits the application range of PC. Owing to its excellent fiber forming ability, thermal stability and chemical stability, polytetrafluoroethylene (PTFE) could be applied as a kind of anti-dripping agent in the production of thermoplastic resins. In this work, a kind of novel fluorinated acrylate coated PTFE composite anti-dripping agent (PTFE@PFAC particle) was successfully prepared with the PTFE as the core layer and methyl methacrylate, butyl acrylate, and fluorinated acrylate as the shell layer. The diameter of the PTFE@PFAC particle is in the range of 200–250 nm. After melt blending with PC, PC/PTFE@PFAC composite was successfully prepared. It is found that the addition of a certain amount of PTFE@PFAC particles has little influence on the processability, transparency, crystallinity, tensile strength and thermal stability of PC/PTFE@PFAC composites. Surprisingly, the addition of a small amount of PTFE@PFAC (0.5 wt %) can significantly improves the anti-dripping and flame retardance properties of the composite, which was reflected in the extension of anti-dripping time, the increase of ultimate oxygen index, the significant reduction of heat release rate and the total smoke production.
