摘要
Abstract
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.关键词
