外文摘要：Dyes are important source of water pollution and their degradation products may be carcinogens and toxic to mammals. For evaluation of oxidative degradation of dye wastewater, the kaolinite supported zero valent iron were synthesized. The surface morphology of kaolinite and kaolinite supported zero valent iron were observed with scanning electron microscopy (SEM) and transmission electron microscopy (TEM). The degradation of dye C.I. Reactive Red 15 in aqueous solution by kaolinite supported zero valent iron was investigated in details. The effects of the dosage of kaolinite supported zero valent iron, pH in solution, reaction time and the initial dye concentration on the degradation were studied. The results showed that the pH value, the dosage of kaolinite supported zero valent iron and the initial dye concentration had an important impact on dye degradation. Under these conditions, such as 80 mg/L dye C.I. Reactive Red 15, 20 min of reaction time, 0.5 g kaolinite supported zero valent iron particles, pH value of 2.0, temperature of 308 K and 120 rpm respectively, the degradation rate of dye C.I. Reactive Red 15 reached 82.3%. ? 2019 Technoscience Publications. All rights reserved.
