摘要

采用水热法制备了ZnO纳米粒子催化剂。利用一些技术（FE-SEM、TEM和EDX）研究了纳米颗粒的性质。研究了紫外光催化降解Maxillon Blue（GRL）的工艺。在不同的实验条件下，氧化锌作为催化剂在光催化过程中的应用。影响因素包括质量催化剂的作用和马西隆蓝（GRL）染料的浓度。结果表明，随着ZnO纳米粒子催化剂重量的增加，光催化效率从每200毫升0.1克增加到0.4克，而且当ZnO纳米粒子的量增加时，降解速率先上升，然后在一定范围内保持不变，但当量达到每200毫升0.4克时，降解率略有变化。最高的光降解效率达到87%，表明具有良好的表面活性。

Enhanced Photocatalytic Degradation of Maxillon Blue Dye (GRL) by Using ZnO NPs in Aqueous Solutions

The ZnO nanoparticles (ZnO NPs) catalyst was prepared using the hydrothermal method. Properties of nanoparticles were investigated by utilising some techniques (FE-SEM, TEM, and EDX). The photocatalytic degradation of Maxillon Blue (GRL) under UV irradiation has been studied. The use of zinc oxide as a catalyst in the photo catalysis process under different experimental conditions. The influence of several factors includes the effect of mass catalyst and the concentration of Maxillon blue (GRL) dye. Through the results, the photocatalytic efficiency increases by increasing the weight of the ZnO NPs catalyst starting from 0.1 to 0.4 g per 200 mL, also when the amount of ZnO NPs increased, the rate of degradation goes up first and then keeps unalterable on a certain scale, but when the quantity reaches to 0.4 g per 200 mL, the rate of degradation shows slight change. The highest photodegradation efficiency reaches 87% indicating a good surface activity.

期刊介绍： Asia, as a whole region, faces severe stress on water availability, primarily due to high population density. Many regions of the continent face severe problems of water pollution on local as well as regional scale and these have to be tackled with a pan-Asian approach. However, the available literature on the subject is generally based on research done in Europe and North America. Therefore, there is an urgent and strong need for an Asian journal with its focus on the region and wherein the region specific problems are addressed in an intelligent manner. In Asia, besides water, there are several other issues related to environment, such as; global warming and its impact; intense land/use and shifting pattern of agriculture; issues related to fertilizer applications and pesticide residues in soil and water; and solid and liquid waste management particularly in industrial and urban areas. Asia is also a region with intense mining activities whereby serious environmental problems related to land/use, loss of top soil, water pollution and acid mine drainage are faced by various communities. Essentially, Asians are confronted with environmental problems on many fronts. Many pressing issues in the region interlink various aspects of environmental problems faced by population in this densely habited region in the world. Pollution is one such serious issue for many countries since there are many transnational water bodies that spread the pollutants across the entire region. Water, environment and pollution together constitute a three axial problem that all concerned people in the region would like to focus on.
