In the current study, several nanosized hydrated ferric oxide (HFO)-loaded polymer sorbents were prepared and assayed to examine the effect of HFO loadings on arsenate sorption from aqueous solution. Batch and column sorption studies showed that the sorption capacity of arsenate increased with the increase of HFO loadings from 3 to 15% (in Fe mass); however, a further increase in the HFO loadings resulted in a dramatic decrease of the sorption capacity. At relatively low arsenate levels (e.g., En ligne : http://pubs.acs.org/doi/abs/10.1021/ie800275k [article] Arsenate removal from aqueous media by nanosized hydrated ferric oxide (HFO)-loaded polymeric sorbents : effect of HFO loadings [texte imprimé] / Qingjian Zhang, Auteur ; Bingcai Pan, Auteur ; Weiming Zhang, Auteur ; Bingjun Pan, Auteur . - 2008 . - p. 3957–3962.
