摘　　要：将改性后的羟基磷灰石通过紫外光接枝固载于棉布以制备重金属离子吸附布。采用正交法以及单因素分析法探讨了单体用量、光引发剂用量、交联剂用量、光照时间等工艺因素对镉离子吸附量的影响。采用扫描电镜观察了负载羟基磷灰石吸附布的形貌。结果表明,当光引发剂用量为2%(对单体质量)、光照时间为8min、甲基丙烯酸甲酯质量分数为20%、N,N′-亚甲基双丙烯酰胺用量为1%(对单体质量)时,吸附布吸附性能优异。光照时间对吸附量的影响显著。Modified hydroxyapatite was immobilized on cotton cloth via UV-initiated photografting. The effects of monomer, initiator, cross linker, and irradiation time on adsorption amount were determined using orthogonal and single factor test and the cotton cloth immobilized with modified hydroxyapatite was observed with SEM. The good adsorption property was achieved when initiator amount was 2% （the mass ratio of monomer）, irradiation time was 8 min, methyl methacrylate mass fraction was 20%, N,N＇-methylene bisacrylamide amount was 1%（the mass ratio of monomer）. The irradiation time showed the great impact on the amount of adsorption.
