| 摘 要： | 采用溶胶—凝胶法合成了纳米级ZrO2,运用透射电镜对产品进行了表征,测得其平均粒径为20～30nm。研究了纳米级ZrO2对红、黄、棕3种偶氮染料溶液的吸附。试验了染料初始浓度、pH值、吸附比、吸附时间对吸附率和吸附量的影响,确定了最佳吸附条件。并用红色染料溶液进行了吸附方程的研究。比较了不同洗脱剂洗脱效果。同光催化降解印染污染相比,本法具有吸附快速、脱色效果好的特点,为印染废水处理提供了方法。但本法的工业化问题有待进一步深入研究。

| Abstract: | A series of experiments were conducted to study the dye adsorbing characteristics of nano-sized ZrO_2, which was prepared by Sol-Gel process and examined using a transmission electronic microscope, average grain size of ZrO_2 being within the range of 20-30nm. The experiments studied the variables - initial concentration of dye, pH, time and adsorption rate on adsorption of different mono-dyestuffs (red, yellow or brown) on nano-ZrO_2, indicating the potential application of nano-sized ZrO_2 to wastewater treatment. |
