摘要
文章研究了钛酸丁酯溶胶-凝胶法改性天然沸石的方法以及改性条件对改性沸石(Zeo-Ti)去除水体砷效果的影响。结果表明TiO2含量越高,Zeo-Ti去除砷的效果越好;300℃下制得的Zeo-Ti除砷效果最好;与天然沸石相比,Zeo-Ti对As的去除能力显著提高,吸附过程符合langmuir等温吸附模式。
Natural zeolite was modified by titanium dioxide (Zeo-Ti),and was used to adsorb the As in the wastewater. The results indicate that Zeo-Trs adsorption capacity for As (Ⅲ) and As (Ⅴ) increased distinctly compared to natural zeolite, and the adsorption isotherm matched the Langmuir model.
