Abstract Among the arsenic species in the environment, arsenate predominates under oxidizing conditions in soils and waters. The adsorption of As(V) by some natural Fe oxyhydroxides and clay minerals and synthetic Al(OH)3 and FeOOH has been studied. The results show a very high As(V) adsorption capacity on both synthetic Al hydroxide (122 mg/g at pH: 5) and Fe oxyhydroxide (76 mg/g at pH 5). This adsorption capacity is pH dependent and shows maximum values at ~pH 4. The application of these… 
Arsenate Adsorption onto aluminium and Iron (Hydr)Oxides as an alternative for Water Treatment.
The geochemical fates of iron and arsenic are so closely correlated that methods of arsenic removal from water are in general based on the high adsorptive affinity of this metalloid with iron
Adsorption Characteristics of Aqueous Arsenic(III) and Arsenic(V) in Taiwan Soils
This study investigate the adsorption characteristics of aqueous arsenate (As(V)) and arsenite (As(III)) in Taiwan soils namely pinchen, chunliao and baiho. The results from the batch adsorption
Arsenic immobilization in the contaminated soil using poorly crystalline Fe-oxyhydroxy sulfate
TLDR
The result showed that the low crystalline FeOS can be used as a suitable additive for arsenic immobilization in soils and easily mobile arsenic phase was transferred to less mobile phase.
