| 摘 要： | 采用化学沉淀法,分别使用亚铁溶液、高铁溶液以及两者的混合溶液对T-ZnO进行表面改性,利用扫描电子显微镜(SEM)比较了不同改性结果的表面覆盖情况以及EDX测试元素含量。其表面Fe附着量(质量分数)分别为1.89%、3.76%、2.77%。采用TEOS在T-ZnO表面预涂覆SiO2层,将表面Fe的吸附量提高了3倍左右,达到12.73%。

| Abstract: | Three different solutions Fe2+,Fe3+ and the mixture of them were used for magnetic modification on the surface of T-ZnO.The samples prepared by three methods were characterized by XRD,SEM and EDX.The results show that Fe contents on the surface of each sample are 1.89wt%,3.76wt% and 2.77wt%.Using TEOS to function with T-ZnO first,the amount of Fe covered on surface of T-ZnO is raised to 12.73wt%. |
