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 [26–28], 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.
