Abstract
With the aging of the global population and continued economic development, the use of sartan-type antihypertensive drugs (e.g., losartan (LOS), telmisartan (TEL), and valsartan (VAL)) has increased with widespread contamination issues. However, the effect of advanced oxidation processes (AOPs) on the degradation of sartans remains unknown. Therefore, AOPs such as the Fe(II)/peroxymonosulfate (PMS) system and ozonation were used to treat the typical sartans, which led to the formation of various transformation products (TPs). This research involves the formation mechanisms of these TPs following AOPs including aldolization, hydroxylation, ring cleavage, carbonylation and cyclization. The risk evaluation focused on the biodegradability and toxicity of the drugs and their TPs, assessed using computerized toxicity prediction software. The findings indicated that the biodegradability of most TPs was generally poor and most TPs exhibited acute/chronic toxicity. This underscores the need for caution when applying AOPs in water treatment to prevent secondary contamination and suggests the potential necessity of integrating AOPs with complementary purification technologies. This research provides novel insights into the degradation pathways and environmental risks of sartans, emphasizing the importance of a holistic approach to water treatment.
期刊介绍:
The Journal of Water Process Engineering aims to publish refereed, high-quality research papers with significant novelty and impact in all areas of the engineering of water and wastewater processing . Papers on advanced and novel treatment processes and technologies are particularly welcome. The Journal considers papers in areas such as nanotechnology and biotechnology applications in water, novel oxidation and separation processes, membrane processes (except those for desalination) , catalytic processes for the removal of water contaminants, sustainable processes, water reuse and recycling, water use and wastewater minimization, integrated/hybrid technology, process modeling of water treatment and novel treatment processes. Submissions on the subject of adsorbents, including standard measurements of adsorption kinetics and equilibrium will only be considered if there is a genuine case for novelty and contribution, for example highly novel, sustainable adsorbents and their use: papers on activated carbon-type materials derived from natural matter, or surfactant-modified clays and related minerals, would not fulfil this criterion. The Journal particularly welcomes contributions involving environmentally, economically and socially sustainable technology for water treatment, including those which are energy-efficient, with minimal or no chemical consumption, and capable of water recycling and reuse that minimizes the direct disposal of wastewater to the aquatic environment. Papers that describe novel ideas for solving issues related to water quality and availability are also welcome, as are those that show the transfer of techniques from other disciplines. The Journal will consider papers dealing with processes for various water matrices including drinking water (except desalination), domestic, urban and industrial wastewaters, in addition to their residues. It is expected that the journal will be of particular relevance to chemical and process engineers working in the field. The Journal welcomes Full Text papers, Short Communications, State-of-the-Art Reviews and Letters to Editors and Case Studies
