    Abstract:

    With the rapid development of industry, the problem of water pollution is becoming more and more serious and threatening human health.Therefore, the removal and treatment of water pollutants is imminent. With the successful preparation of high-performance adsorbents, adsorption technology has become one of the most promising technologies. β-cyclodextrin polymer not only retains the hydroxyl group and cavity structure with adsorption sites in cyclodextrin structure, but also solves the problems that cyclodextrin monomer is easy to dissolve and has poor stability in water, which has attracted much attention in removing water pollutants. However, β-cyclodextrin polymers have different adsorption properties due to different preparation methods. Based on this, the structural characteristics and preparation methods of four kinds of cyclodextrin polymers, which are cross-linked, star-shaped, linear and immobilized, are described in detail, and the adsorption mechanism and application of heavy metals, dyes, endocrine disruptors and other pollutants in water pollutants in recent years are summarized, and their future development is prospected.
