Abstract

-FeOOH and 􀀃-FeOOH nanoparticle adsorbents for As(V) and As(III) removal were evident from the XRD diagrams, where the oxides appeared in the form 􀀂-FeOOH and 􀀃-FeOOH. The SEM image of the prepared samples revealed that the nanoparticles diameter was about 30 nm. The maximum adsorption capacities of 􀀃-FeOOH for As(V) and As(III) were 77.28 and 78.65 mg/g; and 􀀂-FeOOH were 63.75 and 88.99 mg/g, respectively. After 15 min, about 97–98% of initial As (III) and As(V) concentration (0.05mg/L) was removed from the solution using 1000 mg/L adsorbent. 􀀂-FeOOH and 􀀃-FeOOH nano particles became a promising adsorbent for the removal of As(V) and As(III) from groundwater.
