摘要
目的：饮用水和废水消毒过程中的腐殖酸（HA）化合物被认为是剧毒、致癌和致突变性消毒副产物的前体。本研究的目的是系统地回顾所有关于光催化降解腐殖酸的研究，并评估这些研究的实验室条件和结果。内容：本系统综述是通过搜索Scopus、PubMed和web of science数据库进行的，直到2021年12月。考察了催化剂类型、催化剂大小、最佳pH、腐殖酸的最佳初始浓度、最佳催化剂浓度、最佳时间、光照和去除效率等参数。综述：共筛选了395项研究，使用纳入和排除标准，共有20项研究符合我们的纳入标准，并为纳米颗粒光催化降解腐殖酸提供了必要的信息。在所研究的研究中，据报道，纳米颗粒光催化降解腐殖酸的比例超过70%，在一些研究中，去除率达到100%。展望：从本系统综述的结果来看，使用纳米颗粒的光催化过程对腐殖酸的降解有很高的影响。
A systematic review of photocatalytic degradation of humic acid in aqueous solution using nanoparticles.
Objectives: Humic acid (HA) compounds in the disinfection processes of drinking water and wastewater are considered as precursors of highly toxic, carcinogenic and mutagenic disinfectant by-products. The aim of this study was to systematically review all research studies on the photocatalytic degradation of humic acid and to evaluate the laboratory conditions and results of these studies.
Content: The present systematic review was performed by searching the Scopus, PubMed, and web of science databases until December 2021. The parameters of type of catalyst, catalyst size, optimum pH, optimum initial concentration of humic Acid, optimum catalyst concentration, optimum time, light used and removal efficiency were investigated.
Summary: 395 studies were screened and using the inclusion and exclusion criteria, in total, 20 studies met our inclusion criteria and provided the information necessary to Photocatalytic degradation of humic acid by nanoparticles. In the investigated studies, the percentage of photocatalytic degradation of humic acid by nanoparticles was reported to be above 70%, and in some studies, the removal efficiency had reached 100%.
Outlook: From the results of this systematic review, it was concluded that the photocatalytic process using nanoparticles has a high effect on the degradation of humic acid.
期刊介绍：
Reviews on Environmental Health (REVEH) is an international peer-reviewed journal that aims to fill the need for publication of review articles on hot topics in the field of environmental health. Reviews on Environmental Health aims to be an inspiring forum for scientists, environmentalists, physicians, engineers, and students who are concerned with aspects of human health, including quality of life, that are determined by physiological and psychosociological interactions between man and physical, chemical, biological, and social factors in the environment.
Reviews on Environmental Health is an important niche served by no other journal, that’s being a site where thoughtful reviews can be published on a variety of subjects related to both health and environment. One challenge is to bridge the research on environmental causes of disease with the clinical practice of medicine. Reviews on Environmental Health is a source of integrated information on environment and health subjects that will be of value to the broad scientific community, whether students, junior and senior professionals, or clinicians.
