在氮气保护下高温碳化以聚丙烯酸(PAA)为模板的凹凸棒土(ATP)水凝胶，制得凹凸棒土多孔吸附材料(PA)。经乙烯基三乙氧基硅烷(YDH-151)有机改性，提高了该多孔吸附材料的亲油性。应用扫描电镜、红外光谱分析、BET比表面积测试等多种方法对吸附材料进行分析表征，研究了YDH-151对凹凸棒土的改性效果、凹凸棒土多孔材料的介孔结构、选择吸附性能和可回收再利用性能。结果表明，由YDH-151改性的凹凸棒土多孔吸附材料(OPA)具有良好的多孔性、亲油性、选择吸附性、可再生性。

Polyacrylic acid (PAA) templet in attapulgite (ATP)/PAA hydrogel was carbonized under nitrogen atmosphere at high temperature for preparing a new porous, lipophilic absorbent material, and the porous ATP (PA) was modiifed by vinyltriethoxysilicon (YDH-151). The SEM, FT-IR and BET and other methods were used to characterize the organic modiifed ATP composite (OPA). The modiifcation effect of OPA and the macroporous structure, selective adsorption, recyclable properties of the spongy adsorbent material were researched thoroughly. The results showed that the adsorbent material OPA, with functional spongy structure, lipophilic, and recyclability, possesses excellent and selective adsorption for organic contaminants.
