| 摘要: |
| 通过化学分析法测定了水化硅酸钙（C S H）吸附氯离子的能力；通过核磁共振法和拉曼光谱法测定了水化硅酸钙的结构.结果表明：水化硅酸钙吸附氯离子的能力与其结构密切相关，水化硅酸钙平均链长约为4时，其吸附氯离子的能力最强；氯盐阳离子促进了水化硅酸钙链长的增加，使其吸附氯离子的能力增强；与钠离子相比，钙离子更能促进水化硅酸钙链长的增加，从而使其吸附更多的氯离子. |

| Abstract: |
| The ability of adsorption of chloride ion by calcium silicate hydrate(C S H) was tested by a chemical analysis method, and C S H structure was determined by nuclear magnetic resonance（NMR） spectroscopy and Raman spectroscopy The results show that the chloride ion adsorption ability of calcium silicate hydrate is closely related to its structure The calcium silicate hydrate with the average chain length of about 4 has the strongest chloride ion adsorption ability The cation of chloride salt promotes increasing average chain length of the calcium silicate hydrate, and enhances its chloride ion adsorption ability Compared with the sodium ion, calcium ion promotes better increasing average chain length of the calcium silicate hydrate, thereby adsorbing more chloride ions. |
