摘要多酸本来的含义就是杂原子亦或是多原子在氧原子配位桥的作用下在一系列固定不变的结构下形成的一类含氧酸。其中他独有的酸性、假液相行为还有多功能性这几方面的特点，让它化学领域备受关注，同时对它的研究和探索也备受期待。

    在工业水平不断提高的今天，全世界以及全球的环境污染变得越来越严重，同时也对日趋稀有的水资源造成了越来越严重的破坏和污染，所以我们要通过化学的手段去去除有机染料去改善我们的环境，让污染程度最大程度上的降低，因此像亚甲基蓝这种污染环好、境，具有毒性，造成严重污染的化学物质，应该极力的抵制，用化学商铺端改善环境问题同样也受到了化学界乃至社会的一至关注，也成为环保绿色生活的重要工作。杂多酸的巨大优点就是，在保持着良好的酸性的和催化性的同时，还能很好的分解染料和具有良好的酸和氧化催化性能，毒性相对偏低，同时它的优点就是对于环境没有污染，绿色环保，同时反应的过程比较平稳，活性相对比较高，没有一丝丝腐蚀性。由于光在催化的情况下可有效将有机污染物转化为无污染的分子，同时对现有能源的利用率低实验步骤相对其它更加简易，反应的过程相对平稳，同时没有重复的污染，这些个显而易见的优点得到了越来越多的关注。本论文研究Co-Anderson 型杂多酸的制备方法实验步骤以及知道产物的结构，了解杂多酸的应用，性质还有种类，并对产物结构通过XRD和红外谱图进行结构表征。71081

Abstract Polyacid reason Yoshiko Hiraki multiatomic distribution Constant congruent atomic coordination Bridged compositional one type containing acidic name. Specific acidity, "Liquid Liquid" Act, Multifunctional Novelty etc Excellent occupation area Medium - echelon relations.

While its research and exploration is also highly anticipated

With the development of industry, the ecological environment is increasingly damaged, especially the limited water resources are polluted, the removal of organic dyes in water, such as methylene blue and other toxic and harmful chemical substances, environmental protection has become an important task.Heteropolyacids as a solid acid, with good acid and oxidation catalytic properties, can effectively degrade the wastewater of dyes and other organic pollutants, and there are low toxicity, do not pollute the environment, high activity, mild reaction conditions, Non-corrosive equipment and other characteristics. As the photocatalytic degradation can effectively convert organic pollutants into inorganic small molecules, to achieve the purpose of completely inorganic, and has low energy consumption, easy operation, mild reaction conditions, no secondary pollution and other prominent advantages and popular attention. Many difficult to remove or use other methods difficult to remove organic pollutants can be removed by photocatalytic degradation.

In this paper, the preparation method of Co-Anderson type heteropoly acid was studied and the structure of the product was known. The application of heteropoly acid was studied. The properties of the product were characterized by XRD and IR spectra.

Keywords: heteropoly acid, catalysis, cobalt sulfate
