摘要： Provided are a method for preparing an adsorbent from industrial vermiculite, an adsorbent and application thereof. The method comprises steps: flaking and de-polluting the raw industrial vermiculite ore to obtain industrial vermiculite fine flakes; grinding the industrial vermiculite fine flakes to obtain industrial vermiculite powder; mixing the industrial vermiculite powder with a binder and granulating it to obtain an industrial vermiculite granular; and post-treating the industrial vermiculite granular to obtain the adsorbent. The adsorbent is prepared by the method. Applications may include purification of benzene gases such as toluene, sewage treatment, horticulture, soil improvement and applications in agricultural carriers. The adsorbent of the disclosure has the advantages of high cation exchange capacity, large internal specific surface area, strong adsorption of toluene and lightweight porous, etc. Moreover, the preparation method of the disclosure is simple, green, low production cost and easy to be produced on a large scale.
