Abstract

Nowadays, water quality is increasingly at risk due to human activities, climate change and the emergence of new pollutants, including pharmaceuticals and pathogens. Advanced oxidation processes, particularly those involving peroxymonosulphate (PMS) activation by heterogeneous catalyst have garnered significant attention from the scientific community. In this context, metal-organic frameworks (MOFs) have demonstrated considerable potential as catalysts for PMS activation. In this research, a copper-based MOF, Cu(BTC)-(TMIB), was successfully synthesized using 1,3,5-Tris(1H-imidazol-1-yl)methylbenzene (TMIB) and 1,3,5-benzenetricarboxylic acid (BTC) as ligands. Novel use of Cu(BTC)-(TMIB) as a PMS catalyst shows strong activity and efficient sulphate radical generation. To enhance stability and operational control in continuous water treatment processes, Cu(BTC)-(TMIB) was immobilized onto polyacrylonitrile (PAN) nanofibre membranes via electrospinning. Membrane performance was validated in both batch and continuous flow systems. In batch experiments, the 3%Cu(BTC)-(TMIB)-9%PAN membrane achieved the required pathogen inactivation in 15 minutes, complete destruction of clozapine in less than 1 hour and complete antipyrine removal in less than 24 hours. Under continuous flow conditions, the system operated stably for 216 hours, performing 36 cycles with a constant and high-efficient pathogen and contaminant removal.

Cu(BTC)-(TMIB)- pan膜作为病原体消毒和药物降解的创新方法：在流动系统中的可行性研究

如今，由于人类活动、气候变化和新污染物（包括药物和病原体）的出现，水质面临越来越大的风险。先进的氧化工艺，特别是涉及过氧单硫酸盐（PMS）的多相催化剂活化已经引起了科学界的极大关注。在此背景下，金属有机骨架（MOFs）作为PMS活化催化剂已显示出相当大的潜力。本研究以1,3,5-三（1h -咪唑-1-酰基）甲苯（TMIB）和1,3,5-苯三羧酸（BTC）为配体成功合成了铜基MOF Cu(BTC)-(TMIB)。新型的Cu(BTC)-(TMIB)作为PMS催化剂具有较强的活性和高效的硫酸盐自由基生成。为了提高连续水处理过程的稳定性和操作控制能力，采用静电纺丝法将Cu(BTC)-(TMIB)固定在聚丙烯腈（PAN）纳米纤维膜上。在间歇流和连续流系统中验证了膜的性能。在批量实验中，3%Cu(BTC)-(TMIB)-9% pan膜在15分钟内达到了要求的病原体灭活，在不到1小时内完全破坏氯氮平，在不到24小时内完全去除安替比林。在连续流动条件下，系统稳定运行了216小时，进行了36个循环，持续高效地去除病原体和污染物。

期刊介绍： Water Research, along with its open access companion journal Water Research X, serves as a platform for publishing original research papers covering various aspects of the science and technology related to the anthropogenic water cycle, water quality, and its management worldwide. The audience targeted by the journal comprises biologists, chemical engineers, chemists, civil engineers, environmental engineers, limnologists, and microbiologists. The scope of the journal include: •Treatment processes for water and wastewaters (municipal, agricultural, industrial, and on-site treatment), including resource recovery and residuals management; •Urban hydrology including sewer systems, stormwater management, and green infrastructure; •Drinking water treatment and distribution; •Potable and non-potable water reuse; •Sanitation, public health, and risk assessment; •Anaerobic digestion, solid and hazardous waste management, including source characterization and the effects and control of leachates and gaseous emissions; •Contaminants (chemical, microbial, anthropogenic particles such as nanoparticles or microplastics) and related water quality sensing, monitoring, fate, and assessment; •Anthropogenic impacts on inland, tidal, coastal and urban waters, focusing on surface and ground waters, and point and non-point sources of pollution; •Environmental restoration, linked to surface water, groundwater and groundwater remediation; •Analysis of the interfaces between sediments and water, and between water and atmosphere, focusing specifically on anthropogenic impacts; •Mathematical modelling, systems analysis, machine learning, and beneficial use of big data related to the anthropogenic water cycle; •Socio-economic, policy, and regulations studies.
