简介：建立了以纳米二氧化钛（TiO2）作为吸附剂填充微柱，电感耦合等离子体质谱（ICP-MS）法测试Cu^2＋，Cd^2＋，Pb^2＋和Ni^2＋离子的分析方法．考察了不同pH值、洗脱液浓度、样品流速、体积和外源干扰离子的影响，实验结果表明在pH值8～10范围内待测离子可被TiO2定量吸附，2．0molL^-1HNO3可将吸附在微柱上的待测物完全洗脱，优化条件下本方法对溶液中Cu^2＋，Cd^2＋，Ph^2＋和M^2＋离子检出限分别为：0．02，0．01，0．01，0．02μgL～，相对标准偏差小于2％（n=7），富集系数50倍．对水系沉积物标准物质（GBW07310）的测定值与标准值相一致，方法具有简便、快速，灵敏度高，重现性好的优点，可满足河口水体与沉积物样品中痕量金属元素定量分析的要求．

简介：以工业水玻璃为硅源,表面活性剂十六烷基三甲基溴化铵为结构模板剂,利用室温晶化法合成出MCM-41介孔分子筛,并以钛酸丁酯为前驱体,通过溶胶凝胶法及液相沉积法对介孔分子筛MCM-41进行纳米TiO2的组装。运用XRD、FT-IR、N2吸附-脱附等表征手段对其结构特征和氧化钛分散状态进行了研究,结果表明：TiO2与MCM-41端基硅氧键反应形成Ti-O-Si键;纳米TiO2不仅进入孔道,较均匀地修饰了介孔分子筛MCM-41的孔壁,而且使介孔分子筛MCM-41仍保持有序的孔道结构。

简介：通过溶胶-凝胶法结合光催化还原法制备掺Mo^6＋附Ag的TiO2纳米颗粒,并在可见光下对酸性大红3R进行降解实验,研究其在可见光下的催化活性,并与纯TiO2、仅掺Mo^6＋或仅附Ag的TiO2进行对比。进一步讨论在可见光照射下掺杂量、焙烧温度等因素对掺Mo^6＋附Ag纳米TiO2降解性能的影响。结果表明：可见光下Ag/Mo6＋/TiO2比纯TiO2、仅掺Mo6＋或仅附Ag的TiO2显示出更高的活性,这是因为金属Mo6＋的掺杂和贵金属银的沉积使二氧化钛的吸收带边发生红移,拓宽了可见光的响应范围;Ag/Mo^6＋/TiO2催化剂的催化活性最高时的Mo^6＋掺杂量为4.5%,银的附着量为2%。焙烧温度为500℃,这种掺Mo6＋附Ag纳米TiO2对酸性大红3R的降解率可达87.6%.
