Abstract
Abstract
Arsenic contamination is a severe issue because of its toxicity and related health risks. This review article presents an overview of the sources, health hazards, and treatment options for arsenic pollution. Conventional approaches to achieving the permitted level of 10 ppb set by the WHO, such as chemical oxidation, biological oxidation, and coagulation–flocculation, are ineffective and time-consuming. The paper analyses the advantages and disadvantages of various advanced treatment technologies, including membrane filtration, ion exchange, advanced oxidation, phytoremediation, and adsorption. This paper summarized the effectiveness of hybrid arsenic remediation techniques in removing arsenic and its operating conditions. This study is a helpful tool for putting remediation strategies into practice. This article describes arsenic pollution's damaging effects on human health, underscoring the necessity for careful treatment. The article addresses numerous treatment technologies, each with advantages and disadvantages preventing widespread use. Due to these limitations, deciding the best technique for arsenic remediation is difficult. As a result, hybrid treatment systems are urgently needed, with photocatalysis-adsorption being the most popular approach. The relevance of adaptable, user-friendly, low-maintenance hybrid technologies that are versatile, easy to use, and provide affordable arsenic removal options, especially for poor populations, is highlighted by prospects.
