| 摘 要： | 采用光沉积-液相化学法调节电子流向，构建了直接Z型TiO2/Ag/Ag3PO(4 )(TAAPO)光催化材料.通过扫描电子显微镜(SEM)、透射电子显微镜(TEM)、X射线衍射仪(XRD)、X射线光电子能谱(XPS)、紫外-可见漫反射光谱仪以及光致发光(PL)光谱仪等手段对其进行表征，并对其在可见光照射下催化降解环丙沙星(CIP)的性能进行了研究.结果表明，当水体pH为3.0,催化剂分散浓度为0.3 g/L,CIP的初始浓度为15 mg/L时，光催化降解体系能够取得最佳的去除效果.在该组条件下，光照120 min CIP的降解率约为99%,并且在经历4个循环后仍然保持了良好的降解效果.在光催化降解CIP的过程中，主要反应活性物种为超氧自由基(·O2

| Abstract: | Selecting the index to reflect the development level of public libraries, this paper analyses the development level of public libraries including 31 provinces and municipalities in China by using the factor analysis method. The analysis result shows that？the development level of？public libraries？in each area？is restricted by？the develop- ment level of local economies,？and is influenced by？its？size. With the development of information technology, public libraries should？improve the？management and service level？by using new technology. |
