Abstract
Humic aicd (HA) and iron oxides or zero-valent iron with iron oxides shell can coexist, and their interaction alter their ability to adsorb pollutant in the environment. The influence of HA on arsenic adsorption onto three types of irons (zero-valent iron, hematite and magnetite) was investigated with different contact order using batch sorption experiments. The results indicated that the presence of HA led to a decrease in the arsenic adsorption, and the order of the amounts of As adsorption were found to follow as: As-Fe > (HA-As)+Fe > (HA-Fe)+As. These results can have important implications to design the arsenic pollution remediation system and understand the behavior of arsenic in natural environmental system.
