Abstract: The present invention relates to an organic polymer adsorbent, an organic polymer adsorbent composition, and a method for preparing an organic polymer adsorbent and, more specifically, to an organic polymer adsorbent to be used for a ventilation device such as a desiccant dehumidifier. According to the present invention, an adsorbent material is changed to an organic polymer adsorbent such that the mechanical stability and durability of the material itself can be ensured, and the specific surface area of interconnected inner pores and adsorbents and the size of formed pores can be controlled since toluene is contained as a pore generator of the adsorbent. Therefore, the adsorbent of the present invention has superior adsorption performance over that of other conventional organic polymer adsorbents containing a salt-type carboxyl group and has remarkably improved desorption performance, and thus has an effect of very remarkable energy efficiency.

Abstract: The method and materials of this invention make possible substantially faster techniques for organic-aqueous extractions and routine chemical reactions work-ups. The inventive material uses silicone elastomer-coated glass powders, magnetic powders, and sponges as absorbents to extract organic products from an aqueous mixture. After separation from the mixture, these different forms now loaded with organic products can serve as a convenient input for flash chromatographic separations or other processing. With these techniques, tedious liquid-liquid extractions are replaced by a simple solid filtration or transfer and emulsion formation is eliminated. These versatile sorbents can also be used for larger scale work-ups, various extractions of organics from an aqueous solution (e.g., water purification) or gas phase and various analytical or other applications.
