Bimetallic coordination polymer for highly selective removal of Pb(II): Activation energy, isosteric heat of adsorption and adsorption mechanism

Yingbi Chen et al.

Summary: The bimetallic coordination polymer adsorbent Ti/Zr-DBMD shows excellent performance in efficiently removing toxic Pb(II) from water within a pH range of 3-7. It exhibits low activation energy, spontaneous exothermic behavior, and strong regeneration capability. Competitive adsorption experiments and mechanism analysis further confirm its potential for Pb(II) removal.

Effect of different DOM components on arsenate complexation in natural water

Fan Zhang et al.

Summary: The study found that different components of dissolved organic matter (DOM) exhibit varying binding capacities for arsenic, with humic substances showing the strongest affinity. In eutrophic water systems, polysaccharides may be the main DOM component binding arsenic. The presence of cationic bridge function is more likely to occur in the presence of humic substances.

Antifouling and antibacterial behavior of membranes containing quaternary ammonium and zwitterionic polymers

Ming-Ming Zhu et al.

Summary: A dual-functional ultrafiltration membrane containing quaternary ammonium and zwitterionic polymers was designed to overcome organic/bio-fouling, with improved hydrophilicity and antibacterial properties. The membrane showed higher flux recovery, lower protein adhesion, and efficient broad-spectrum antibacterial performance against S. aureus and E. coli. It effectively inhibited bacterial adhesion for long-term antibacterial properties, demonstrating potential for microbiologically contaminated water filtration processes.

Removal and formation of perfluoroalkyl substances in Canadian sludge treatment systems - A mass balance approach

Narasimman Lakshminarasimman et al.

Summary: This study evaluated the behavior of thirteen PFAS in nine Canadian sludge treatment systems and found significant changes in mass flows of target PFAS through different treatment processes. Pelletization and alkaline stabilization processes led to an increase in PFAS mass flow, while some digestion processes resulted in a modest reduction. Long chain PFAS showed varying behaviors in different systems, while short chain PFAS exhibited an increasing trend in some systems.

PFAS and DOM removal using an organic scavenger and PFAS-specific resin: Trade-off between regeneration and faster kinetics

Fuhar Dixit et al.

Summary: Treatment technologies like ion exchange show potential in removing toxic PFAS from natural waters, but the use of PFAS-specific resins can lead to increased resin demand and operational costs. Comparative studies found that PFAS-specific resin had faster uptake kinetics for PFAS and removed some DOM, while regenerative organic scavenger resin required longer contact times for PFAS removal. Despite differences in resin breakthrough, both IX resins showed similar levels of PFAS and DOM removal before exhaustion.

Recent progress in the detection of emerging contaminants PFASs

Heejeong Ryu et al.

Summary: PFASs are persistent anthropogenic chemicals that are difficult to degrade in the environment. While current detection methods heavily rely on chromatographic techniques coupled with mass spectrometry, alternative methods such as optical and electrochemical techniques have been extensively explored for simple, accessible, inexpensive, rapid, and sensitive detection of PFASs. These alternative methods aim to overcome the limitations of expensive instrumentation, professional operators, complicated sample pretreatment, and considerable analysis time associated with chromatographic techniques.
