1. 研究目的与意义及国内外研究现状

水污染日趋严重的今天，为了找出最适宜tio2降解甲基橙的反应环境，为了更好的了解自己的专业所涉及的领域，为了将自己学到的理论知识更好的运用到实际当中，同时也是为了更顺利的毕业以及决定毕业之后自己打算选择的就业方向，必须做好这次选题。

因为它让我充分的了解到自己学习到的专业知识的价值，写好了自己未来的人生规划，理论转为实践需要这一次重要的探索。

并且地球是我们每一个人的家园，呵护它是每个人的责任，然而现在满目疮痍的它依然在保护着我们，即使个人的力量是渺小的，即使会失败，这种努力也是值得的，因为每一次小小的收获，都会推动治理染料废水着巨大的历史任务的前进。

2. 研究的基本内容

研究以纳米二氧化钛为催化剂光催化降解甲基橙是我这次试验的研究对象，甲基橙作为染料废水的重要组成部分，对其进行降解的工作刻不容缓。

不同的反应环境对降解结果的影响是我主要的实验内容，其中包括，反应的光源强度，反应的ph以及温度的变化对甲基橙降解率的影响。

3. 实施方案、进度安排及预期效果

实验室准备好了反应的仪器，需要自己制作纳米二氧化钛，配置甲基橙溶液。

考虑到多组人员都要用到仪器，三周左右的时间必须完成实验。

5种光源强度，250w，300w，350w，400w，500w；每次光源为一组，一组做5种不同ph的降解环境。
