以异丙醇钛为前体,十二烷胺为模板剂,采用配体辅助模板法合成高比表面积多孔二氧化钛材料,利用氮气吸附对其孔径性质进行分析。通过静态吸附实验研究了多孔二氧化钛对刚果红的吸附行为,考察了吸附时间、温度、搅拌速度、吸附剂用量和初始浓度对刚果红吸附效果的影响。分别在相关条件下,结果表明:当吸附时间为30min时,脱除率达98%以上;吸附温度为45℃时,脱除率可达98%;摇床转速为160r/min时,脱除率达到最大;当吸附剂使用量为0.10g时,脱除率能够达到98%左右,已能够满足应用要求;多孔二氧化钛吸附刚果红的吸附量与刚果红初始浓度成正比。

Porous Titanium oxide was synthesized by a ligand assisted template method using docecylamine as the template and titanium isopropoxide as the precursor. The as-synthesized titanium dioxide was characterized by nitrogen adsorption. The adsorption behavior of Congo Red by the porous TiO2 was studied by static adsorption experiment. The effects of adsorption time,temperature,stirring speed,adsorbent dosage and initial concentration of Congo Red on the adsorption performance were investigated. Results showed that when the adsorption time reached 30 min,the removal rate can be more than 98%;when the adsorption temperature was 45℃,the removal rate can reach 98%;when the stirring speed was 160 r/min,the removal rate was the maximum;when the catalyst dosage was 0.10 g, the removal rate can reach 98%,which met the requirements of application;the Congo Red adsorption capacity by porous titanium dioxide was found to be proportional to the initial concentration of Conge Red solution.
