Thông tin mô tả:
This study evaluated the effectiveness of a readily prepared zirconia nanoparticle in removing arsenite (As(III)) from aqueous solution. It was demonstrated, without pre-oxidation of arsenite, the sorbent was highly effective for As(III) removal with a maximum adsorption capacity of 1.85 mmol-As/g. The sorbent
had a high adsorption capacity toward As(III) at pH 5–10, and the optimal pH was around 8. The kinetics studies showed that most of the arsenite uptake occurred rapidly in the first 10 h, and the adsorption equilibrium was obtained within 48 h.
