摘要: A two-level three-factor (23) full factorial design was conducted to observe the parameters influencing arsenic removal from an aqueous solution using iron oxide-coated A. niger biomass. The factors taken into consideration were mass of adsorbent, concentration in and temperature. It observed that adsorbent temperature had positive effects on efficiency. Arsenic a negative effect. This meant higher concentration, lower As effect more pronounced As(III) (26.6%) compared As(V) (14.4%). be case (30.7%) (25.5%).
