博士 === 國立中央大學 === 化學學系 === 103 === The well-ordered cubic large-pore mesoporous silicas LP-FDU-12 (Fm3m) and the cubic mesoporous silicas SBA-16 (Im3m) were both synthesized successfully via co-condensation of tetraethyl orthosilicate (TEOS) and carboxyethylsilanetriol sodium salt (CES), also functionalized with different ratio of catboxylic groups under acidic conditions, and using triblock copolymer Pluronic F127 and Pluronic P123 as template. The former were called LP-FTC-x series, and the latter were called S16C-x series. The LP-FTC-x were used as adsorbents for immobilization of papain and lysozyme and the S16C-x were used as adsorbents for removing of the dyes. These processes were systematically studied by varing time, initial concentration and pH. The LP-FTC-30 showed an excellent adsorption capacity for 895 mg papain per gram adsorbent, and the S16C-30 showed an excellent adsorption capacity for 561 mg methylene blue per gram adsorbent. The isotherm models, kinetic models and intraparticle diffusion models properties were used to analyze the immobilization mechanism of LP-FTC-x and the adsorption mechanism of S16C-x. The data were both fitted to the Langmuir isotherm model and Pseudo-Second-Order kinetics.
