Summary: In this study, a heterogeneous system of goethite/oxalate under UVA irradiation was proven effective in removing ASA from aqueous phase through photodegradation. The presence of oxalate significantly enhanced the efficiency of ASA degradation, and acid conditions were more favorable for the reaction. The study also revealed the important role of center dot OH and detected the formation of inorganic arsenic and ammonia during the photodegradation process.

Summary: This study examined arsenite (As(III)) removal in a goethite/oxalate suspension under UVA-irradiation, finding that pH, oxalate concentration, and goethite dosage significantly affected removal efficiency. Increasing pH decreased photo-oxidation efficiency but increased adsorption efficiency, while the addition of oxalate promoted As(III) removal. The use of appropriate amounts of goethite accelerated removal, with different mechanisms observed for As(III) removal under neutral and acidic conditions.

Summary: Bi4O5Br2 with irregular flake shape was synthesized via a facile hydrolysis method and exhibited excellent visible-light-induced photocatalytic activity towards carbamazepine oxidation. Photogenerated holes and superoxide radical anions were identified as the main active species during the oxidation process. After 120 min of visible light exposure, the carbamazepine solution was pollution-free, and the as-synthesized Bi4O5Br2 showed good chemical stability and reusability in photodegradation processes.

Summary: Antibiotics, as common emerging contaminants, pose potential risks to aquatic ecology and human health due to their widespread and extensive use. This study investigated the photodegradation behaviors of sulfamethoxazole (SMX) and enrofloxacin (ENR) in water under UV and simulated solar light. The degradation rates of SMX under the two light sources were 0.235 min(-1) and 0.024 min(-1), respectively, and ENR were 0.124 min(-1) and 0.043 min(-1), respectively. The study explored the effects of various factors on the photodegradation behaviors and proposed a potential photodegradation pathway. Understanding the characteristics and mechanisms of photodegradation of these antibiotics may contribute to the development of efficient techniques for their removal from water.

Summary: Different from traditional dye sensitization, this work achieves electrostatic interaction under irradiation by using electron trapping sites and positively charged rhodamine B dye molecules. The surface oxygen vacancies of Bi2MoO6 gather electrons and tightly bind to the positive dye molecules, reducing the oxidized dyes and participating in the photocatalytic degradation of levofloxacin. The cyclic path formed by the newly aggregated electrons on the oxygen vacancies greatly reduces electron-hole recombination, increasing the efficiency of levofloxacin degradation under LED irradiation.

Summary: A simplistic solvothermal process was used to fabricate novel amorphous TiO2-BiOBr-Bentonite (A-TiO2-BiOBr-Bt) multidimensional photocatalysts in a practical and economically feasible manner. The stickiness of the A-TiO2-BiOBr-Bt wet cake and the low drying temperature make it a suitable composite for the fabrication of the photoreactive inner coating of water treatment containers. The A-TiO2-BiOBr-Bt photocatalyst with a mass ratio of 1:1:2 displayed high surface area, low bandgap, and low electron-hole recombination rate.

Summary: This study investigated an enhanced photochemical Fenton-like system for the degradation of antibiotic sulfadiazine (SDZ). The results showed that the UV/Fe(II)/SC system had the highest degradation rate and efficiency. Dissolved substances such as HCO3-, SO42-, and NO3- in the water environment inhibited the degradation of SDZ, and the concentration of SDZ and high concentration of humic acid (HA) decreased the degradation rate of the target compound. Four degradation pathways were proposed based on the identification of photodegradation products of SDZ.

Summary: During the Covid-19 pandemic, there may be limited supply of raw materials such as corn and soybean meal for livestock and poultry feeds, leading to a growing interest in using palm kernel cake as an alternative. The chemical composition of palm kernel cake varies depending on the method of oil extraction, with acceptable levels of crude fiber for ruminants but considered high for poultry. Biodegradation through solid-state fermentation can enhance the nutritional quality of palm kernel cake.

Summary: The study demonstrated that dietary supplementation of ADS18-Se significantly improved egg yolk color, antioxidant profile of egg yolk and breast meat. Total cholesterol showed a significant decrease (p < 0.05) in fresh and stored egg yolk and breast muscle in the Se treated groups compared to the control groups. Eggs from hens fed with organic Se remained fresh for two weeks compared to inorganic Se and basal diets. Egg yolk color, antioxidant profile, and oxidative status of egg yolk and tissue were enhanced with dietary organic Se supplementation (ADS18 > Se-Yeast).

Summary: This study aimed to investigate the effects of replacing antibiotics with postbiotics and paraprobiotics on growth performance, small intestine morphology, immune status, and hepatic growth gene expression in broiler chickens. The results showed that the dietary treatments did not significantly affect the growth performance indicators, but did significantly impact feed intake, abdominal fat, colon mucosa sIgA, histomorphology, and growth gene expression. It was concluded that postbiotics and paraprobiotics can replace antibiotics without compromising the growth performance, carcass yield, and immune status of broiler chickens.
