Porous silica surface was treated with hydrobromic acid in excess at a low temperature of-10~0℃,in a solution of silane coupling agent of pH 3.5~4.0 adjusted with acetic acid,and bromine-containing active film/silica composites were prepared.The surface structure was characterized with X-ray photoelectron spectroscopy and scanning electron microscopy.The bromine at the surface of the composite was characterized with infrared spectrum.The bromine contents were measured with fluorescent X-ray spectroscopy after cold water or boiling water treatment,respectively.An active film with stable structure was formed on the surface of the silica composite,onto which bromine was grafted with a mass concentration as high as 0.34%.The bromine content at the surface of the composite was found to decrease after washing with water and hot water was more effective than cold water.In addition,the samples treated by water and then bromine showed higher bromine contents than the ones treated by bromine and then water.After the composites were washed for 30 min by cold water or boiling water,the bromine content of the former decreased to 0.15% and 0.13%,respectively,and the bromine content of the latter decreased to 0.09% and 0.03%,respectively.
