Abstract null null In this study, an amphoteric magnetic chitosan (CS)-based flocculant MFe3O4@CS-g-PIA was prepared from CS, Fe3O4, and itaconic acid (IA), and its apparent morphology and characteristic structure were systematically studied. The flocculation performance and mechanism of the fabricated material were also investigated in different pollution systems, and the effects of total monomer concentration, m(CS):m(IA), IA pre-neutralization degree, reaction temperature, reaction time, and ...

Abstract null null Electrochemical processes such as electrocoagulation (EC) and electrooxidation (EO) have proved their effectiveness for the treatment of industrial refractory wastewater. This study aimed to strategically combine EC and EO processes for the treatment of highly contaminated wastewater (COD of 10,360 ± 665 mg/L and phosphorus concentration of 22.9 ± 0.9 mg/L) coming from industrial container wash water (IWW). In this regard, the EO and EC processes were investigated individually...

Abstract null null Utilization of F-T synthetic to produce value-added C8 linear α-olefin is a promising alternative approach, however, the purification of α-olefin from F-T synthetic products is a great challenge, especially for removing 2-methyl-1-heptene (MH). This article addresses the novel method of etherification reaction to remove MH from F-T synthetic products, and develop by far the most efficiency reactive distillation (RD) method to intensified the etherification process. The scarcit...

Abstract null null Inorganic membranes hold great potential for various mainstream applications such as in wastewater treatment, drug manufacturing, food and beverage production, and dairy purification. There are numerous commercially available ceramic membranes which possess high corrosion resistance, high strength, and good heat resistance. However, these membranes are still prone to fouling causing a considerable decline in membrane performance and hence shorter life-times. Conventional metho...

Abstract null null Mixed matrix membranes (MMMs) are promising candidates for organic solvent nanofiltration (OSN), but the thick separation layer and poor compatibility between polymer and fillers are two critical challenges needed to be solved. Herein, a series of tetrakis(4-carboxyphenyl)porphyrin (abbreviation: TCPP) based metal–organic frameworks (MOFs, M−TCPP (M=Zn, Cu, Co, Ni)) have been synthesized in the form of two–dimensional nanosheets, which were then used as thin fillers in P84 mat...

Abstract null null Herein, a magnetic amine-functionalized mesoporous silica SBA-15 (Fe3O4@SBA-15-PDA/HBP-NH2) adsorbent was fabricated by loading Fe3O4 nano-particles on amino-terminated hyperbranched polymers (HBP-NH2) functionalized SBA-15 and exploited for chromium (VI) and uranium (VI) elimination. The morphologies and microstructures of as-obtained materials were observed using different physicochemical and spectroscopic techniques. Meanwhile, batch experiments were performed to investigat...

Abstract null null Herein, the alkynyl groups are grafted on g-C3N4 via ball milling of g-C3N4 and CaC2. The successful functionalization of g-C3N4 by alkynyl is demonstrated by Fourier transform infrared spectroscopy and X-ray photoelectron spectroscopy. Ultrathin wrinkle-like structure with abundant pores is observed for the resulted alkynyl functionalized g-C3N4 nanosheets, which can furnish abundant photocatalytic active sites. The photocatalytic NH3 production rate of 0.12 mmol·gcat-1·h-1 i...

Abstract null null Four asymmetric alkyl-substituted DAPhens (N,N’-Dimethyl-N,N’-Dialkyl-2,9-Diamide-1,10-Phenanthrolines) were synthesized and investigated as selective ligands for UO22+. The results confirm that the ligands have higher affinity for uranyl comparing to the symmetric analogues with the same 1,10-phenanthroline core moiety. The slope analysis indicated the formation of 1:1 (metal/ligand) extracting complex, which was identified in the organic phase as [UO2(DAPhen-4)(NO3)]+ comple...

Abstract null null A hybrid catalyst system consisted of MWCNT and Co-TiO2 through simple physical mixing was applied for peroxymonosulfate activation for antipyrine degradation. With 2 mM peroxymonosulfate, the removal rate of antipyrine is significantly increased from 53.24% and 86.23% to 100% in the presence of same weight of 0.2 g/L MWCNTs, Co-TiO2, and MWCNTs/Co-TiO2 (half/half) mixture, respectively in 12 minutes. The influence of various parameters, including the ratio of Co-TiO2/MWCNT, c...

Abstract null null In this study, a magnetic Fe3O4@SiO2@La2O3 nano-catalyst with a core-shell structure was synthesized to improve the efficiency of catalytic ozonation of cinnamyl alcohol. The structure, morphology, and elemental composition of the catalyst were analyzed with the help of catalyst characterization methods. The mechanism of strengthened degradation efficiency and mineralization of cinnamyl alcohol in catalytic ozonation system in the existence of the catalyst were further discuss...
