Abstract
Chromium is a common pollutant in water, soil and other media in nature, which is discharged from modern industrial processes.The Science and technologies for the abatement of chromium are greatly concerned, because the excess intake of chromium leads harm to organisms.In this paper, the recent research progress of layered double hydroxides ( LDHs ) used as sorbents in removing chromium and the adsorption mechanisms were summarized.The mechanism and influencing factors of LDHs and modified LDHs were also compared.Adsorption properties of calcinated LDH and composites of LDHs with other materials were introduced.Ion exchange, dissolution and precipitation, reconstruction are the main adsorption mechanism of LDHs on Cr removal.关键词
