TiO₂-PES Fibrous Composite Material for Ammonia Removal Using UV-A Photocatalyst

引用

Journal of Materials Science and Chemical Engineering 2024年第1期12卷 1-19页

作者： Anh Phuong Le Thi masaru Ohshiro Takaomi Kobayashi Department of Science and Technology Innovation Nagaoka University of Technology Nagaoka Japan Kasai Corporation Niigata Japan

This study focused on the development and characterization of TiO2-PES composite fibers with varying TiO2 loading amounts using a phase inversion process. The resulting composite fibers exhibited a sponge-like structure with embedded TiO2 nanoparticles within a polymer matrix. Their photocatalytic performance for ammonia removal from aqueous solutions under UV-A light exposure was thoroughly investigated. The findings revealed that PeTi8 composite fibers displayed superior adsorption capacity compared to other samples. Moreover, the study explored the impact of pH, light intensity, and catalyst dosage on the photocatalytic degradation of ammonia. Adsorption equilibrium isotherms closely followed the Langmuir model, with the results indicating a correlation between qm values of 2.49 mg/g and the porous structure of the adsorbents. The research underscored the efficacy of TiO2 composite fibers in the photocatalytic removal of aqueous under UV-A light. Notably, increasing the distance between the photocatalyst and the light source resulted in de-creased hydroxyl radical concentration, influencing photocatalytic efficiency. These findings contribute to our understanding of TiO2 composite fibers as promising photocatalysts for ammonia removal in water treatment applications.

[Background] Medical staff have many occasions to be exposed to anticancer drugs (ACDs) in the process of performing cancer chemotherapy. Although guidelines for the safe handling of ACDs have been published, actual measures against exposure to ACDs differ between hospitals, and no surveillance data regarding the conditions of each hospital in relation to performing chemotherapy in Japan are available. [Methods] To understand current measures against exposure to ACDs and problems related to cancer chemotherapy at outpatient departments, we conducted a questionnaire survey on doctors, pharmacists, and nurses in 10 leading hospitals for cancer chemotherapy in Japan. [Results] Responses were received from all 10 institutions. The hospital pharmacists prepared all ACDs for outpatients in each institution. All hospitals took basic measures against ACD exposure, such as using personal protective equipment and penetration-resistant waste containers. Conditions against exposure to ACDs generally improved between 2012 and 2015, especially in terms of conveyance of ACDs and use of a closed-system drug transfer device. However, no measures linking ACDs with administration routes or injection sites were commonly taken in any of the hospitals in 2015. [Conclusions] Conditions against ACD exposure improved between 2012 and 2015, possibly because new guidelines were issued. To improve measures for ACD exposure in Japan, preparing more appropriate manuals and offering more opportunities to medical staff for continuing education are considered important.

Kawasaki disease(KD)is a vasculitis of unknown etiology occurring predominantly in children under five years old[1].Coronary artery aneurysm,its most serious complica-tion,occurs in about 25%of untreated patients[2].High-dose intravenous immunoglobulin(IVIG)2 g/kg is used to prevent coronary artery aneurysms[1,3,4],but about 20%of patients are nonresponsive and require a second dose for a total of 4 g/*** appropriate timing of live attenuated vaccine(LAV)administration in such cases is unclear.

Based on four phases of TM images acquired in 1990, 1995, 2000 and 2005, this paper took Kitakyushu in Japan as a case study to analyze spatial change of land use landscape and corresponding effects on environmental issues guided by landscape ecology theory in virtue of combining technology of Remote Sensing with GIS. Firstly, land use types were divided into 6 classes （farmland, mountain, forestland, water body, urban land and unused land） according to national classification standard of land use, comprehensible ability of TM image and purpose of this study. Secondly, following the theory of landscape ecology analysis, 11 typical landscape indices were abstracted to evaluate the environmental effects and spatial feature changes of land use. Research results indicated that land use has grown more and more diversified and unbalanced, human activities have disturbed the landscape more seriously. Finally, transfer matrix of Markov was applied to forecast change process of land use in the future different periods, and then potential land use changes were also simulated from 2010 to 2050. Results showed that conversion tendency for all types of land use in Kitakyushu into urban construction land were enhanced. The study was anticipated to help local authorities better understand and address a complex land use system, and develop improved land use management strategies that could better balance urban expansion and ecological conservation.
