    關鍵字: This study focused on arsenate removal in aqueous solution under various pH conditions. The results reveal that higher arsenate removal can be obtained in acidic environment rather than in base condition. Kinctic analysis suggests that arsenate removal can be described as a first-order reaction for all pH values studied;the reaction rate constants were 0.76 (pH=4), 0.16(pH=7),and 0.04min-1 (pH=9). In addtion , as a result of sorption investigation, the sorption performance was 43.62 (pH=4), 42.73 (pH=7), and 37.48 mg As/g iron (pH=9).
