摘　　要：本文采用简单的水热法,以(NH4)2SiF6为原料,在L-异亮氨酸(L-Ile)的辅助下合成了由纳米管组成的微球状ZnOHF。根据FESEM和TEM结果,可以通过改变反应时间来控制产物的形貌,制得ZnOHF的形貌经历了由片层球到纳米管组成的微球。ZnOHF因为其良好的性质,可以用做吸附剂。本文采用纳米管组成的微球状ZnOHF对MB染料进行暗室脱色吸附研究。通过对其吸附过程进行动力学研究,发现此过程的吸附等温线符合Langmuir二级动力学模型。Employing (NH4)2SiF6 as fluorine source, ZnOHF hierarchical microspheres composed of nanotubes were prepared by a simple hydrothermal method with the aid of L-Isoleucine. According to the results of FESEM and TEM, the morphology of the product can be controlled by changing the reaction time. The morphology of ZnOHF varies from lamellar spheres to nanotubes. Because of its good properties, ZnOHF can be used as adsorbent. In this paper, the decolorization and adsorption of MB dyes by microspheroidal ZnOHF composed of nanotubes were studied in dark chamber. It is found that the adsorption isotherm of the adsorption process accords with Langmuir second-order kinetic model.
