| 摘要: 研究了几种硅藻土的表面羟基结构、表面酸性质及其孔结构,发现除浙江白土表面具有双生的硅羟基外,其他只有连生与孤立的硅羟基；硅藻土中均存在少量的B酸和L酸；硅藻土酸性质及经NH4Cl或HCl活化后的酸性质变化与硅藻土孔结构、表面结构有关。焙烧温度升高,硅藻土酸强度增加,酸量减少。 |

| Abstract: In thispaper, surface structure, pore structure and surface acid sitepropertiesof several kinds diatomitewere studied Itwas found that therewas joined hydroxyl groups in Zhejiang white soil, only isolated and adjacent hydroxyl groups were found in other diatomite. Also
there was some Lacid and B acid in diatom ite The acid site p roperties of diatom ites untreat-ed aswell as treated with NH4Cl or hydrochloric acidwere all concernedw ith pore structure,surface structure of diatom ite. As roast temperature increased, the acid site strength of diatomite increased, and the acid site amount gradually decreased. |
| Keywords: diatomite acid site property structure |
