Various treatment technologies have been employed for Sb and As removal, including coagulation [12], [13], membrane separation [14], [15], and ion exchange [16], [17]. However, these technologies bear with several disadvantages. For instance, the removal efficiency of coagulation highly depends on the physicochemical properties of the raw water and the process can result in the formation of large amounts of toxic by-products [18], [19]. Sorption has been considered as one of the most feasible and practical approaches due to its simple operation, cost effectiveness, minimal sludge production, and regeneration capability [20]. Among the commonly reported sorbents, namely, activated alumina [21], carbon-based materials [22], biosorbents [23] and so on, iron-based materials including zero valent iron (ZVI) [24], [25], iron oxides [26], [27], [28], and iron-based bimetal oxide [29], [30] are considered to be the most promising and effective sorbents due to high surface reactivity, environmental friendliness, and abundance on earth.Since adsorption is regarded as the best available technology for inorganic arsenic removal in community-scale water supply systems
