摘　　要：对多孔玻璃微珠作为多孔性固体吸附剂的研制及其在液相中的吸附性能做了初步研究 .研制出适合于制作多孔玻璃微珠的Na2 O -B2 O3-SiO2 系统玻璃组分 .设计了新型的玻璃微珠成珠设备及工艺 .利用该组分的玻璃经研磨、成珠、分相、酸溶和膜化等处理方法 ,制得了直径为 1～ 10 μm ,孔径约为 10nm的多孔玻璃微珠 .用氮吸附静态容量法 ,测得了多孔玻璃微珠的氮吸附等温线、比表面和孔分布曲线 .通过多孔玻璃微珠对苯酚、聚氧乙烯醚和聚丙二醇等有机物的吸附实验 ,给出多孔玻璃微珠对它们的吸附等温线 .并指出合理的吸附温度、大的比表面和适当的膜化工艺对提高多孔玻璃微珠的吸附量都是有效的 .As a porous solid adsorbent, porous glass microspheres were prepared and its adsorption feature in liquid phase was investigated. The Na 2O-B 2O 3-SiO 2 system was used to manufacture porous glass microspheres with a novel device. The procedures include grinding, phase separation, acid treatment and membranous dealing. The poruous glass microspheres with diameters of 1-10 μm and pore size of 10 nm were obtained. The adsorption properties of the microspheres were characterized by adsorption isotherm, specific surface and pore distribution with the help of N 2 adsorption. The adsorption isotherms of phenol, polyoxyethylene ether and polypropylene glycol were tested, based on which effective means to increase the adsorption of porous glass microsphere is proposed.
