| 英文摘要 | The desiliconization reaction in sodium aluminate solution was studied by adding tricalcium hydroaluminate (C(3)AH(6)). C(3)AH(6) prepared at 323 K has a relatively high desiliconization capacity. Kinetic results show that the desiliconization reaction is first-order in SiO(2) concentration, and the apparent activation energy is estimated to be 96 kJ/mol between 363 and 393 K, which is lower than that from adding Ca(OH)(2). During the desiliconization process, SiO(2)(OH)(2)(-) ions enter the interior of C(3)AH(6) particles and react with them further. As a result, the distribution Of SiO(2) in the desiliconization product (DSP) is more uniform than that from adding CaO. Also, the SiO(2) content in DSP is higher. (C) 2008 Elsevier B.V.
