Description

technical field

[0001] The invention relates to the technical field of adsorbents, in particular to a method for preparing an environmentally friendly attapulgite anti-sedimentation adsorbent for construction. Background technique

[0002] Adsorbents are solid substances that are effective in absorbing certain components from a gas or liquid. Adsorbents generally have the following characteristics: large specific surface, suitable pore structure and surface structure; strong adsorption capacity for adsorbate; generally do not chemically react with adsorbate and medium; easy to manufacture and easy to regenerate; good mechanical properties strength etc.

[0003] The patent document with the patent number CN102824892B discloses an adsorbent, preparation method and application for removing dioxins from waste incineration waste gas, including (1) grinding and crushing the attapulgite raw soil, and sorting out particles with a particle size of 3mm Attapulgite clay with a part...
