Efficient adsorption and reduction of Cr(VI) from aqueous solution by Santa Barbara Amorphous-15 (SBA-15) supported Fe/Ni bimetallic nanoparticles

Xiaowei Xing et al.

Summary: This study proposes a novel mesoporous Santa Barbara Amorphous-15 supported Fe/Ni bimetallic composite (SBA-15@Fe/Ni) for the removal of Cr(VI) contaminants in the water environment. The results show that SBA-15@Fe/Ni exhibits better stability and removal efficiency, and maintains excellent performance in the presence of various competitive ions.

Enhanced removal of 2,4-dichlorophenol by Fe-Pd@ZIF-8 via adsorption and dechlorination

Xiulan Weng et al.

Summary: Recently, bimetallic Fe-Pd nanoparticles integrated with metal organic frameworks (MOFs) have shown potential for enhanced organic contaminant removal. Fe-Pd@ZIF-8 composite catalyst demonstrated a higher removal efficiency of 2,4-dichlorophenol compared to ZIF-8 or Fe-Pd alone. Characterization of Fe-Pd@ZIF-8 revealed that the removal mechanism involved both adsorption and dechlorination.

Conductive-polymer-supported palladium-iron bimetallic nanocatalyst for simultaneous 4-chlorophenol and Cr(VI) removal: Enhanced interfacial electron transfer and mechanism

Jituo Xie et al.

Summary: Combining conductive polymers with nanoscale zerovalent iron can effectively address the challenges of nZVI reduction by enhancing reactivity and catalytic ability. Supporting Pd/Fe nanoparticles significantly improves the removal rate of 4-chlorophenol, attributed to the highly stabilized and dispersed state, as well as the synergistic effect of electron transfer.

Performance, Reaction Pathway and Kinetics of the Enhanced Dechlorination Degradation of 2,4-Dichlorophenol by Fe/Ni Nanoparticles Supported on Attapulgite Disaggregated by a Ball Milling-Freezing Process

Hongdan Wu et al.

Summary: The ball milling-freezing-disaggregated attapulgite was used to disperse Fe/Ni nanoparticle clusters into single spherical particles, resulting in the formation of D-ATP-nFe/Ni composite material. This composite material exhibited improved dechlorination degradation of 2,4-dichlorophenol compared to ATP-nFe/Ni, with smaller particle size, larger specific surface area, higher degradation rate, and higher phenol yield. The main dechlorination pathway involved direct reduction to phenol, while the secondary pathway involved the removal of one chlorine atom to generate intermediate compounds.

Use of Parthenium hysterophorus with synthetic chelator for enhanced uptake of cadmium and lead from contaminated soils-a step toward better public health

Ujala Ejaz et al.

Summary: Parthenium hysterophorus is a plant species that can uptake heavy metals from the soil and accumulate them in its tissues. The use of the chelating agent EDTA can enhance metal uptake capacity. The experiment showed that the concentrations of Cd and Pb in the shoot of P. hysterophorus were highest without and with the presence of EDTA, respectively. EDTA also increased the accumulation of essential ions in P. hysterophorus.

Mechanism of Oxytetracycline Removal by Coconut Shell Biochar Loaded with Nano-Zero-Valent Iron

Qi Li et al.

Summary: In this study, different types of biochar were prepared and used for oxytetracycline removal. The optimal conditions were determined for high adsorption capacity, and the adsorption process was found to be dominated by single-molecule chemical adsorption with increasing heat absorption entropy. Mass spectrometry revealed that the removal process included both adsorption and degradation, providing a potentially valuable material for oxytetracycline removal.

Pentachlorophenol and nine other chlorophenols in urine of children and adolescents in Germany - Human biomonitoring results of the German Environmental Survey 2014-2017 (GerES V)

Maria I. H. Schmied-Tobies et al.

Summary: Chlorophenols are a group of chemicals widely used in the production of biocides, pharmaceuticals, and other industrial products due to their biocidal properties. Some chlorophenols are toxic to aquatic life and harmful to humans, possibly causing cancer. A study in Germany from 2014 to 2017 found relatively low levels of chlorophenol exposure in children and adolescents, with levels lower than those found in North America.
