中文摘要：

通过辐射接枝的方法在聚丙烯（PP）纤维上接枝丙烯酸单体,涂覆硅酸钠后经氯化钙交联得到接枝硅酸钙的PP功能化纤维（PP-g-CaSiO3）。红外光谱（IR）和扫描电镜图（SEM）表明硅酸钙成功地接枝到PP纤维表面。BET测试表明,当接枝率为46%时,PP-g-CaSiO3的比表面积高达376.64m2/g。PP-g-CaSiO3对水中双酚A（BPA）表现出良好的吸附性能,饱和吸附量达到39.23mg/g,吸附等温线满足Langmuir模型,吸附动力学符合二级动力学模型。

英文摘要：

The functional fiber（PP-g-CaSiO3） was prepared by coating of sodium silicate（Na2SiO3） and then crosslinking of calcium chloride（CaCl2） on the acrylic acid（AA） grafted polypropylene（PP） fiber.FT-IR spectroscopy,BET measurement and scanning electron microscopy（SEM） analysis indicated that CaSiO3 was successfully grafted onto polypropylene fiber,and the specific surface area of fiber increased significantly.The adsorption of bisphenol A（BPA） on PP-g-CaSiO3 was also studied.The results showed that the data of BPA adsorption on the fiber sample were fitted to the Langmuir isotherm model and second-order kinetics equation,and its saturated adsorption capacity reached 39.23mg/g.
