| Abstract: | This paper reviews the progress of the application of all kinds of surfactants on alumina in the near decade. Combining the results in studying the precursors of alumina oxide,it analyzes the influence on the size, morpha and pore structure of alumina with the sorts of surfactant.It summarizes adsorption mechanism. Several influence factors such as physicochemical properties of adsorbates, pH of the solution as well as ionic strength are discussed in detail. Based on these studies, we prospect the trend of the application of surfactants to synthesis of nano-alumina. |
