In this study, hollow micron zero-valent iron (H-mZVI) was prepared using the ethylenediamine liquid phase reduction method. The microstructures were characterized by SEM, XRD, BET and FTIR. results showed that H-mZVI possessed a spherical structure with particle size of approximately 1 μm. density notably lower compared to solid (S-mZVI). Furthermore, an increase in addition, initially decreased before stabilizing. Results demonstrated degradation efficiency H-mZVI/PS for DEHP 2.96 times higher than S-mZVI/PS. charge system S-mZVI/PS system, exhibited fast electron migration rate strong transport ability between solution interface material. carried out jointly surface reaction on particles homolytic led Fe2+ ions solution. Additionally, contribution free radicals process order SO4-· > ·OH 1O2. There three pathways toxicity products significantly parent.

Photodegradation Pathways of Typical Phthalic Acid Esters Under UV, UV/TiO2, and UV-Vis/Bi2WO6 Systems

Frontiers in Chemistry, Год журнала: 2019, Номер 7

Опубликована: Дек. 13, 2019

Photolysis and photocatalysis of typical phthalic acid esters (dimethyl phthalate, DMP; diethyl DEP; dibutyl DBP) were carried out in UV, UV/TiO2 UV-Vis/Bi2WO6 systems. All selected the decomposition byproducts detected qualitative quantitative analysis through HPLC GC-MS. As results photolysis photodegradation, each system demonstrated different removal ability to DMP, DEP DBP. showed strongest degradation on DMP DEP, while almost had no DEP. However, all systems strong On other side, resulted various pathways PAEs. The UV mainly attacked carbon branch, produced o-hydroxybenzoates. There ring-opening In photocatalytic process, hydroxyl radicals not only but also benzene ring. Therefore, hydroxylated compounds both by GC-MS there fewer products due direct hole oxidation compared with which reacted pollutants radicals.

An Overview of Micro(Nano)Plastics in the Environment: Sampling, Identification, Risk Assessment and Control

Sustainability, Год журнала: 2022, Номер 14(21), С. 14338 - 14338

Advances in urban infrastructure, a flourishing polymer sector, and more traffic have all contributed to rise micro(nano)plastics the environment. Researchers are exploring production, fate, toxicity threshold, severity of micro(nano)plastic exposure. Albeit, understanding sampling protocols, preservation samples, characterization obtained from different mediums (e.g., soil, water, air, living bodies) is still challenging. Particularly identification micro(nano)plastics, on other hand, restricted limited typical generic definition contaminating sources. In addition, before degrade naturally, many challenges must be overcome, enhancing need for research assisted degradation. Thus, systematic review presented, which begins by discussing identification, sampling, handling; then showcases environmental health consequences how control them; finally, it discusses management options. According studies, biological chemical methods break down risen popularity. However, these often only cover one type plastic. Furthermore, solutions can transform polymers into may also produce byproducts, increasing contamination risk. Therefore, control, prevention, strategies investigated generate realistic long-term solutions. The literature suggests combination microorganisms bacterial species) approaches filtration with degradation) could effective treatment micro(nano)plastics. according literature, relevant risks associated humans various exposure routes currently unclear. Likewise, standardization supported sophisticated state-of-the-art apparatus detecting required. Overall, precision strategy selection critical, their usage should regulated if behavior not properly addressed.
