摘要

在本报告中，RuO2@ZnO纳米结构被合成，表征，并用于刚果红(CR)染料从水相去除。考察了接触时间、pH、浓度等因素对吸附效果的影响。结果表明:形成的RuO2@ZnO纳米结构的表面积为21 m2 g-1，孔径为23.5 nm。RuO2@ZnO纳米结构对刚果红的吸附量最高，为102.42 mg/g。平衡数据与Langmuir模型(R2 >0.9338)，吸附动力学符合拟二级方程(R2 >0.9999)。

Congo red pigment weeding out from water media via RuO2@ZnO nanostructure

In this report, RuO2@ZnO nanostructure was synthesized, characterized, and employed for Congo Red (CR) dye removal from the aquatic phase. The influence of sorption factors contact time, pH, and concentration, was examined. The results indicates the formation of RuO2@ZnO nanostructure with surface area of 21 m2 g-1 and pore size of 23.5 nm. . The highest amount of Congo red adsorbed by RuO2@ZnO nanostructure was 102.42 mg/g. Excellent obedience was found between the equilibrium data and the Langmuir model (R2 > 0.9338), whereas the adsorption kinetics was consistent with the pseudo-second-order equation (R2 > 0.9999).
