【摘要】 碘代X-射线造影剂(ICMs)是一种诊断药物,已被广发泛地应用于疾病的诊断。由于现有污水处理的过程很难有效地去除ICMs,在水环境中ICMs常被监测到。尽管其本身毒性较低,但在水处理过程中会与氯、氯胺等消毒剂相互作用,形成有毒的副产物,如碘代三卤甲烷、卤代乙酸、卤代乙腈、卤代乙酰胺,对人类健康有害。因此,去除水环境中的碘化造影剂已成为研究的热点之一。本文介绍了ICMs及其代谢产物的特点,重点讨论了国内外ICMs去除方法(如生物技术、高级氧化技术、吸附技术、电化学技术和光催化技术)的研究进展,并比较了这些去除方法的优缺点。更多还原

【Abstract】 Iodinated X-ray contrast medias(ICMs),one of the diagnostic drugs,have been used widely in disease diagnosis.Conventional water treatment methods are difficult to effectively remove ICMs.ICMs can be generally detected in water environment.ICMs have low toxicity,however,ICMs can interact with disinfectants(chlorine and chloramines) to form iodinated disinfection byproducts(such as iodotrihalomethanes,haloacetic acids,haloacetonitriles,and haloacetamides) in the process of water treatment.These byproducts can harm human health.Therefore,the removal of ICMs has become one of the hotspots.In this work,the ICMs and their metabolites were introduced.The removal methods of ICMs including biotechnology,advanced oxidation process,adsorption technology,electrochemical technology,photocatalysis technology were reviewed.The advantages and disadvantages for these removal methods were compared.更多还原
