摘要
Big adsorption over a wide pH range for both ion As As (III) and (V) in the adsorbent alone and shows a high adsorption capacity for both ion [challenge] As As (III) and (V) insolubilization of arsenic-contaminated soil using the same and arsenic adsorption agents can be used alone and indicates the ability situ insolubilization of contaminated soil, there is provided the use of arsenic adsorption agent and treatment method of heavy metal contaminated water thing. Includes at least the iron-aluminum double hydroxide, for arsenic contaminated soil or arsenic contaminated water in the range of pH3~11, arsenic adsorbent of the present invention comprises, As per unit weight of As (V) and and is characterized by adsorption of (III) is high, the variation rate of As per unit weight of (V) adsorption of 10% or less and is used as a slurry or powder. Insolubilization of arsenic-contaminated soil is characterized with respect to arsenic-contaminated soil, and was added in an amount of ~2.0wt% 0.7wt%, arsenic adsorbent powder, and insoluble arsenic by mixing . None [Selection Figure]
