【摘要】 在本研究中，首先系统地考察了高填料比纸板(以4A沸石为主要填料)制备中助留剂的种类、分子量、电荷量和添加量等对无机物留着的影响，为制备具有光催化功能的二氧化钛复合纸板提供理论和技术支持；接着在实验室采用纸板生产技术制备了具有光催化功能、回收简便、能持续反复使用且在日光下激发有效的二氧化钛复合纸板(以甲基橙为目标降解物)，探讨了纸板中不同植物纤维／陶瓷纤维比及不同定量对纸料留着率、纸板机械强度及纸板吸附和光催化降解性能的影响，并考察了二氧化钛复合纸板对动态甲基橙溶液的光催化降解效果；最后，将二氧化钛与氧化锌进行简单的机械复合，进一步制备了不同比例的氧化锌／二氧化钛复合纸板，探讨了复合纸板中不同氧化锌／二氧化钛比对纸板吸附及光催化降解性能的影响。研究结果表明氧化锌复合纸板在紫外光或日光下对不同偶氮染料的光催化降解性能都优于二氧化钛复合纸板的，且动态偶氮染料水溶液光催化降解效果比二氧化钛复合纸板的大一倍以上。更多还原

【Abstract】 Firstly, effects of the structure, dose, charge density （CD） and molecular weight （MW） of the flocculants on the retention of inorganic materials were investigated to provide theory and technical aids to prepare titanium dioxide （TiO₂） composite sheets with photoeatalytic property this paper. Secondarily the composite sheets with photocatalytic property to methyl orange （MO） under UV or solar light were prepared by a papermaking technique in our laboratory. The sheets were found to be recovered easily from the aqueous solution and to be able to be used repeatedly. The effects of m （plant fiber）/m （ceramic fiber ） ratio in titanium dioxide （TiO₂） sheets and basis weights on the retention rate and photocatalytie property of the sheets were investigated, and the photocatalytic efficiency of the sheets to flowing MO solution was also investigated. Finally, the composite sheets with different mass ratios of TiO₂ and ZnO mixed mechanically were prepared by the same papermaking technique. The effects of the mass ratios on the adsorptive and photoeatalytie properties of the sheets were studied. The results showed that the photoeatalytie efficiency of ZnO sheets to different AZO dyes were larger than that of the TiO₂ sheets, and that the efficiency of ZnO sheets to flowing AZO dye solution was double larger that of the TiO₂ sheets.更多还原
