Abstract

Photodegradation is the chemical conversion of large, toxic, and complex molecules into non-toxic, simpler, and lower molecular weight species due to light exposure. Heterogeneous photocatalysis has sufficient potential to degrade toxic organic pollutants present in wastewater. As industries discharge their effluents containing organic pollutants into natural water bodies, which penetrate into the subsurface through connected pores it is necessary to study this process in natural or tap water. Tap water (TW) is mainly obtained from underground wells having inorganic salts in a minute quantity with a conductivity of 500 μS/cm. TW contains inorganic anions, which affect the photocatalytic activity and photocatalysis process. The aim of this review is to evaluate the effect of TW on the photo-degradation of organic pollutants such as dyes, pharmaceutical products, pesticides, etc., with the support of the literature. The TW had a diverse effect on the photodegradation of organic pollutants; either it may enhance or decrease the rate of pollutants’ photodegradation.

自来水中矿物离子对有机污染物光降解的影响：未来展望

光降解是指由于光照而将大的、有毒的和复杂的分子转化为无毒的、更简单的和分子量更低的物质。多相光催化具有足够的潜力来降解废水中的有毒有机污染物。随着工业将含有有机污染物的废水排放到天然水体中，这些水体通过连通的孔隙渗透到地下，有必要在天然水或自来水中研究这一过程。自来水（TW）主要从地下井中获得，地下井中含有微量无机盐，电导率为500μS/cm。TW含有无机阴离子，影响光催化活性和光催化过程。本综述的目的是在文献的支持下，评估TW对染料、医药产品、农药等有机污染物的光降解作用。TW对有机污染物的光降解具有不同的影响；它可以提高或降低污染物的光降解速率。

期刊介绍： Water (ISSN 2073-4441) is an international and cross-disciplinary scholarly journal covering all aspects of water including water science and technology, and the hydrology, ecology and management of water resources. It publishes regular research papers, critical reviews and short communications, and there is no restriction on the length of the papers. Our aim is to encourage scientists to publish their experimental and theoretical research in as much detail as possible. Full experimental and/or methodical details must be provided for research articles. Computed data or files regarding the full details of the experimental procedure, if unable to be published in a normal way, can be deposited as supplementary material.
