Background: Azo dyes are recognized as non-decomposable and recalcitrant compounds and can be depleted into more dangerous secondary products in anaerobic environments. In the current scenario, different water treatment strategies, including adsorption, photocatalysis, and advanced oxidation processes based practices, are facing different limitations.

Methods: A literature survey was accomplished by searching the scientific data from different search engines, including Scopus, PubMed, Science Direct, Springer, Taylor and Francis, Google Scholar, Blackwell-Synergy, Wiley-Interscience and Research-Gate, etc. This article has been compiled after intensively reviewing about 231 research papers, reviews, and book chapters in the fields of industrial effluents, hazardous materials, and water treatment strategies with their advantages and limitations.

光催化剂（TiO2和ZnO）掺杂的沸石的新兴方面以及降解偶氮染料的高级氧化工艺：综述

背景：偶氮染料是公认的不可分解和难降解的化合物，在厌氧环境中可被消耗为更具危险性的次级产品。在当前情况下，包括吸附，光催化和基于高级氧化过程的实践在内的不同水处理策略都面临着不同的局限性。

方法：通过搜索来自不同搜索引擎的科学数据来完成文献调查，这些搜索引擎包括Scopus，PubMed，Science Direct，Springer，Taylor和Francis，Google Scholar，Blackwell-Synergy，Wiley-Interscience和Research-Gate等。在对工业废水，有害物质和水处理策略领域的231篇研究论文，评论和书籍章节进行了详尽的回顾之后，我们对本书进行了整理，并总结了它们的优势和局限性。
