摘要: ABSTRACTIn this study, the removal of arsenic was evaluated using micellar-enhanced ultrafiltration process. Response surface methodology and Box-Behnken matrix methods were also applied to design experiments determine optimum conditions. Therefore, main operational parameters including pH (4–10), initial concentration (20–80 µg/L), Cetyltrimethylammonium bromide (CTAB) (1–3 mM) investigated. The results analysis variance revealed a good agreement between experimental data built model with determination coefficient (R2) 0.99. Accordingly, efficiency obtained about 94.8% at optimal condition (pH = 6.73, arsenic = 29.44 µg/L, CTAB 2.83 mM).
