TL;DR: In this article , bismuth oxychloride-based plasmon photocatalysts (Bi-Bi3O4Cl) exhibiting high performance were successfully developed by reducing Bi3+ on the surface of Bi3O 4Cl.
Abstract: Photocatalytic oxidation of emerging contaminants (ECs) in water has recently gained extensive attentions. In this study, bismuth oxychloride-based plasmon photocatalysts (Bi-Bi3O4Cl) exhibiting high performance were successfully developed by reducing Bi3+ on the surface of Bi3O4Cl. Consequently, the photocatalysts were used to remove ECs from water. The effects of developmental process and Bi metal plasmon resonance on the photoelectric performances of Bi-Bi3O4Cl were investigated through a series of characterizations. The UV-vis diffuse reflection and photoluminescence spectra revealed that the light absorption range of the photocatalyst gradually increased and the electron recombination rate gradually decreased with the introduction of Bi metals. The optimal removal rates of ciprofloxacin and tetrabromobisphenol A by Bi-Bi3O4Cl were 93.8% and 96.4%; the respective reaction rate constants were 5.48 and 4.93 times higher than that of Bi3O4Cl. The mechanism study indicated that main reactants in the photocatalytic system were •O2- radicals and photogenerated holes, and the existence of oxygen vacancies and Bi metals promoted electron transfer in photocatalyst. In conclusion, this research produces a novel, green, highly efficient, and stable visible light photocatalyst for the removal of ECs from water.

TL;DR: In this article , the removal efficiency, influencing factors, and mechanism of polyamide (PA) particles from wastewater treatment by electrocoagulation was explored, and the results showed that the combination of the iron anode and aluminum cathode (FeAl) achieved the best removal effect.
Abstract: With the increasing accumulation of microplastics in the water environment, it is essential to study the removal of microplastics in current treatment processes. Electrocoagulation is an effective wastewater treatment technique with the advantages of low cost, independence of chemicals, and ease to operation. This study aims to explore the removal efficiency, influencing factors, and mechanism of polyamide (PA) particles from wastewater treatment by electrocoagulation. The effects of electrode materials, applied voltage, initial electrolyte pH, and concentration on the removal of polyamide were systematically investigated. Our results showed that the combination of the iron anode and aluminum cathode (FeAl) achieved the best removal effect. The removal efficiency of microplastics increased with the increase of applied voltage and electrolyte concentration. Considering the energy consumption and cost, the removal efficiency of polyamide particles was 96.82 % after 120 min of electrolysis under the combination of FeAl electrode, with a plate spacing of 2.5 cm, an applied voltage of 10 V, an initial pH of 7, and an electrolyte concentration of 0.02 mol/L. The current study demonstrates the potential of electrocoagulation to remove microplastics from wastewater and provides engineering perspectives on the optimization of operating parameters.
