Investigation and the Effect of Cerium Dioxide on the Removal of Methylene Blue Contaminants from Water

Nowadays Nano Photocatalyst has the ability to treat water contaminated with organic matter because of their photocatalytic properties. One of the organic materials that is widely used in industrial plants is Methylene Blue. Due to its toxicity it also has irreparable effect on the environment. Cerium Dioxide has been widely considered in the field of photocatalytic activity by in incorporating excellent properties such as high corrosion resistance in a variety of corrosive environments photocatalytic properties etc. The popularity of Cerium Dioxide or Ceria is increasing in catalyst applications and in some cases has become a substitute substance. Reducing the size of Ceria particles in nanoscale dimensions has a tremendous effect on its catalytic behavior. In this study Cerium Dioxide nanoparticles were synthesized by hydrothermal method and after taking XRD test and X-Pert program to determine the type of phases formed nanoparticles were formed without any impurities. Subsequently the particle morphology was investigated by SEM test and the photos taken from Cerium Dioxide nanoparticles showed cubic particles. The size of microfibers was measured by the SEM test and the Debye-Scherrer relationship of about 28 nm. Then Cerium Dioxide nanoparticles were used to remove Methylene Blue contaminants and optimum time concentration Methylene Blue and catalyst content were investigated and in each parameter the optimal value was determined in this study.
