摘　　要：以废旧蚕丝为载体,使用原位还原法制备纳米银/废旧蚕丝(Ag/SF),讨论工艺条件对纳米银粒子的制备及负载的影响。以硼氢化钠为还原剂,直接蓝15和直接橙26为目标降解物,探讨不同还原剂浓度条件下Ag/SF的催化降解性能。结果表明:单独使用硼氢化钠无法实现对直接蓝15和直接橙26的有效降解,Ag/SF的催化效率随反应温度和还原剂浓度的升高而上升,直接蓝15和直接橙26的降解率分别为59.70%和82.59%。Waste silk loaded silver nanoparticles(Ag/SF)are prepared by in situ reduction of silk fabric.The ef⁃fects of synthesis conditions on the loading of silver nanoparticles are discussed.The catalytic degradation per⁃formance of nano silver/silk under different concentration of sodium borohydride as reducing agent are investi⁃gated,with Direct Blue 15 and Direct Orange 26 as target degradants.The results show that sodium borohy⁃dride alone can not effectively degrade Direct Blue 15 and Direct Orange 26,and the catalytic efficiency of Ag/SF increases with the increase of reaction temperature and reducing agent concentration,and the degradation rates of Direct Blue 15 and Direct Orange 26 are 59.70%and 82.59%,respectively.
